the following have been taken from this url: http://codeidol.com/csharp/csharp-network/Asynchronous-Sockets/Using-Asynchronous-Sockets
an additional article is this one: http://www.codeguru.com/csharp/csharp/cs_misc/sampleprograms/print.php/c7695/%5C%5Cwww.vt.edu
The Socket object contains methods that utilize the AsyncCallback class to call completion methods when the network functions are finished. This allows the application to continue processing other events while waiting for network operations to complete their work.
The Socket asynchronous methods split common network programming functions into two pieces:
A Begin method that starts the network function and registers the AsyncCallback method
An End method that completes the function when the AsyncCallback method is called
Table 8.1 shows the asynchronous methods that are available to use with Socket objects. Each Begin method has an associated End method to complete the function.

Note Notice that these methods apply only to Socket objects. In .NET Framework release 1, the TcpClient, TcpListener, and UdpClient classes do not include asynchronous methods.
In this section, we’ll walk through the process of using each of the asynchronous Socket methods to process network functions. Then we’ll look at a couple of sample programs that put it all together.
Establishing the Connection
The method used to establish a connection with a remote host depends on whether the program is acting as a server (waiting for clients to connect to it) or a client (attempting to connect to a remote server). For servers, the BeginAccept() method should be used; for clients, the BeginConnect() method is used.
The BeginAccept() and EndAccept() Methods
To accept an incoming connection attempt from a remote client, you must use the BeginAccept() method. Its format is as follows:
IAsyncResult BeginAccept(AsyncCallback callback, object state)
The BeginAccept() method takes two parameters: the name of the AsyncCallback method used to complete the function, and a generic state object that can pass information between the asynchronous methods.
This is how the BeginAccept() method is typically used:
Socket sock = new Socket(AddressFamily.InterNetwork, SocketType.Stream,
ProtocolType.Tcp);
IPEndPoint iep = new IPEndPoint(IPAddress.Any, 9050);
sock.Bind(iep);
sock.Listen(5);
sock.BeginAccept(new AsyncCallback(CallAccept), sock);
This code snippet creates a Socket object and assigns it to a local IP address and TCP port to listen for incoming connections. The BeginAccpet() method defines the method used as the delegate to be used when a connection attempt is detected on the socket. The last parameter passed to the BeginAccept() method is the original Socket object created.
After the BeginAccept() method is finished, the AsyncCallback method defined will be called when a connection attempt occurs. The AsyncCallback method must include the EndAccept() method to finish the socket accept. Here is the format of the EndAccept() method:
Socket EndAccept(IAsyncResult iar);
The IAsyncResult object parameter passes the IAsyncResult value from the associated BeginAccept() method to the EndAccept() method—this is how the BeginAccept() and EndAccept() pairs are matched.
Similar to the synchronous Accept() method, the EndAccept() method returns a Socket object that is used for the new connection with the client. All further communication with the remote client should be done using this Socket object. A sample section from an EndAccept() AsyncCallback method would look like this:
private static void CallAccept(IAsyncResult iar)
{
Socket server = (Socket)iar.AsyncState;
Socket client = server.EndAccept(iar);
.
.
.
}
The name of the AsyncCallback method must match the name used in the BeginAccept() method parameter. The first step in the method is to retrieve the original server socket. This is done using the AsyncState property of the IAsyncResult class. This property passes the original object placed in the BeginAccept() object parameter. Because it is defined as a generic object, it must be typecast into a Socket object.
After the original Socket object is retrieved, the EndAccept() method can obtain a new Socket object for the client connection. The IAsyncResult object parameter should be the same as that passed to the AsyncCallback method.
The client Socket object, once created, can be used just like any other Socket object, using either synchronous or asynchronous methods to read and write data to the socket.
In the end, the BeginAccept()/EndAccept() asynchronous pair produce the same results as the Accept() synchronous method. You will find that this is true of all the asynchronous Begin() and End() methods. This allows them to be used as direct replacements for the synchronous method calls in network programs that need asynchronous behavior.
The BeginConnect() and EndConnect() Methods
For a client application to connect to a remote server using asynchronous methods, you must use the BeginConnect() method. Its format is as follows:
IAsyncResult BeginConnect(EndPoint ep, AsyncCallback callback, Object state)
The first parameter passed to the BeginConnect() method is the EndPoint value of the remote host to connect to. Like the BeginAccept() method, the BeginConnect() method specifies the AsyncCallback method name of the delegate method to call when the connection is ready for completion. The last parameter is a state object that can be passed to the EndConnect() method to transfer necessary data.
Here is an example of BeginConnect() code:
Socket newsock = new Socket(AddressFamily.InterNetwork, SocketType.Stream,
ProtocolType.Tcp);
IPEndPoint iep = new IPEndPoint(IPAddress.Parse("127.0.0.1"), 9050);
newsock.BeginConnect(iep, new AsyncCallback(Connected), newsock);
This code snippet creates a Socket object newsock and an IPEndPoint object iep for the remote host. The BeginConnect() method references the AsyncCallback method (Connected) and passes the original Socket object newsock to the AsyncCallback method.
When the connection is completed, the AsyncCallback method that was declared is called. The AsyncCallback method uses the EndConnect() method to complete the connection.
The format of the EndConnect() method is as follows:
EndConnect(IAsyncResult iar)
Here again, the IAsyncResult object specified pass the object value from the BeginConnect() method. It will be instantiated with the IAsyncResult object returned by the BeginConnect() method. A sample method to use this would look like the following:
public static void Connected(IAsyncResult iar)
{
Socket sock = (Socket)iar.AsyncState;
try
{
sock.EndConnect(iar);
} catch (SocketException)
{
Console.WriteLine("Unable to connect to host");
}
}
The first statement in the AsyncCallback method retrieves the original socket used for the BeginConnect() method call, using the AsyncState property of the IAsyncResult object passed to the AsyncCallback method.
After the original socket is recreated, the EndConnect() method is called, using the IAsyncResult object to point it back to the original BeginConnect() method. Because it is possible that the remote host will not be available, it is good practice to place the EndConnect() method in a try-catch block. If the EndConnect() method is unsuccessful, it will throw a SocketException error.
Sending and Receiving Data
After a connection is established, you will most likely want to send and receive data with the remote host. Asynchronous methods can also be used to do this.
The BeginSend() and EndSend() Methods
The BeginSend() method sends data to a connected socket. The format of this method is as follows:
IAsyncResult BeginSend(byte[] buffer, int offset, int size,
SocketFlags sockflag, AsyncCallback callback, object state)
As you can see, there are plenty of parameters to use with the BeginSend() method. You may notice that most of them are similar to the synchronous Send() method. Walking through them, the first one is the byte array that contains the data you want sent. The offset parameter points to the location within the buffer parameter from which to start sending data, and the size parameter specifies how many bytes from the buffer parameter to send. Next, the sockflag parameter specifies any special socket flags that you want set for the communication. Finally, the AsyncCallback callback and state objects are specified, defining the method to call when the BeginSend() method succeeds and a state object to send information to the EndSend() method.
A sample BeginSend() method would look like this:
sock.BeginSend(data, 0, data.Length, SocketFlags.None,
new AsyncCallback(SendData), sock);
This example sends the entire data buffer and calls the SendData() method when the socket is ready to send the data. The sock Socket object is passed to the AsynCallback() method.
The EndSend() method completes the sending of the data. The format for this method is as follows, where the IAsyncResult parameter defines an empty object that references the result of the BeginSend() method call:
int EndSend(IAsyncResult iar)
The EndSend() method returns the number of bytes successfully sent from the socket.
Here’s an example of the EndSend() AsyncCallback method:
private static void SendData(IAsyncResult iar)
{
Socket server = (Socket)iar.AsyncState;
int sent = server.EndSend(iar);
}
The original sock socket is re-created using the AsyncState property of the IAsyncResult object passed to the AsyncCallback method. Again, this relates to the state object specified in the BeginSend() method.
The BeginSendTo() and EndSendTo() Methods
The BeginSendTo() method is used with connectionless sockets to start an asynchronous data transmission to a remote host. The format of the BeginSendTo() method is as follows:
IAsyncResult BeginSendTo(byte[] buffer, int offset, int size,
SocketFlags sockflag, EndPoint ep, AsyncCallback callback, object state)
As you can see, for the most part the BeginSendTo() method format is similar to the SendTo() method format, with the asynchronous features of the BeginSend() method added. The BeginSendTo() method allows you to specify the EndPoint object of the remote host to which to send the message.
Sample sBeginSendTo() code would look like this:
IPEndPoint iep = new IPEndPoint(IPAddress.Parse("192.168.1.6"), 9050);
sock.BeginSendTo(data, 0, data.Length, SocketFlags.None, iep,
new AsynCallback(SendDataTo), sock);
Again, the only difference between this call and the BeginSend() call is the IPEndPoint of the remote host added to the parameters.
The EndSendTo() method uses the standard format of End methods:
int EndSendTo(IAsyncResult iar)
As always, the IAsyncResult parameter accepts the IAsyncResult value returned by the BeginSendTo() method. The EndSendTo() method returns the number of bytes sent out from the socket.
The BeginReceive() and EndReceive() Methods
The BeginReceive() method accepts data from a remote host on a socket. The format for this method is as follows:
IAsyncResult BeginReceive(byte[] buffer, int offset, int size,
SocketFlags sockflag, AsyncCallback callback, object state)
The first parameter is a byte array that accepts the incoming data. The offset and size parameters are used to specify where in the buffer to start placing the data, and how large the buffer is. The sockflags parameter sets any needed socket flags for the communication. The callback and state parameters allows you to pass information to the EndReceive() method.
Here’s a sample BeginReceive() method call:
sock.BeginReceive(data, 0, data.Length, SocketFlags.None,
new AsyncCallback(ReceivedData), sock);
The BeginReceive() method passes the original socket to the EndReceive() method so that it can re-create the socket for the AsyncCallback method. The AsyncCallback method used for the EndReceive() method would look like this:
void ReceivedData(IAsyncResult iar)
{
Socket remote = (Socket)iar.AsyncState;
int recv = remote.EndReceive(iar);
string receivedData = Encoding.ASCII.GetString(data, 0, recv);
Console.WriteLine(stringData);
}
You see the same AsyncCallback behavior again: the first statement recreates the original socket from the IAsyncResult object. The second statement uses the socket to finish the socket receive, via the EndReceive() method call. Incoming data is placed in the data buffer specified in the corresponding BeginReceive() method call. To access the data buffer from the AsyncCallback method, you must ensure that it is accessible from both methods (such as using a global variable or data class).
The BeginReceiveFrom() and EndReceiveFrom() Methods
The BeginReceiveFrom() method accepts data from any remote host on a connectionless socket. Here is the format:
IAsyncResult BeginReceiveFrom(byte[] buffer, int offset, int size,
SocketFlags sockflag, ref EndPoint ep, AsyncCallback callback, object state)
Notice that the BeginReceiveFrom() method is similar to the BeginReceive() method, except that it specifies a reference to an EndPoint object. The EndPoint object defines the remote host IP address and port number that sent the data.
Warning Remember that the BeginReceiveFrom() method uses a reference to an EndPoint object, not the object itself. It’s easy to forget that ref keyword and thus have a problem on your hands.
A sample BeginReceiveFrom() method would look like this:
sock.BeginReceive(data, 0, data.Length, SocketFlags.None, ref iep, new AsyncCallback(ReceiveData), sock);
The corresponding EndReceiveFrom() method is placed in the appropriate AsyncCallback method:
void ReceiveData(IasyncResult iar)
{
Socket remote = (Socket)iar.AsyncState;
int recv = remote.EndReceiveFrom(iar);
string stringData = Encoding.ASCII.GetString(data, 0, recv);
Console.WriteLine(stringData);
}
The EndReceiveFrom() method returns the number of bytes read from the socket and places the received data in the data buffer defined in the BeginReceiveFrom() method. Again, if you need to access this data within the AsyncCallback method, you should ensure that the data buffer is accessible from both methods.

Using Asynchronous Sockets

Improve Web Application Performance
Introduction
In the IT world, software applications are being rapidly developed. Clients, and so employers, are just looking for those teams/individuals who can build up applications rapidly, just bothering to make their application live; but what often happens after an application goes live is that users start to use the application and it doesn’t respond well. At this point, clients start to lose users and business.To code an application is not a big deal; I believe it can be done by virtually anyone, meaning it is not necessary to have great knowledge or experience. Improving performance of an existing application (especially an one put together rapidly) could be quite risky and could cause many ripple effects. Things must be planned first to avoid horrible results.The following are a few points that can make a site scalable and reliable; but which may initially slow down development. I believe that overall, when maintenance and future changes are taken into account, total development time would be reduced.
1. Minimize HTTP based Requests
2. HTTP Compression:
3. Correct Formatted Images at the Right Place:
4. Compress CSS, JavaScript and Images
5. CSS at Top
6. Javascript at Bottom
7. Content Delivery Network: (CDN)
8. Ajax
9. Ajax vs. Callback
10. Reduce Cookie size
11. Use Cache appropriately
12. Upload compiled code rather than source code
Following are few good practices to gain better performance:
- For HTTP compression, GZip is considered the most effective and most popular by means of browsers and HTTP server. It can reduce file size up to 70% in size.
- Always keep JavaScript and CSS in external files.
- Avoid redirects until needed. Server.Transfer is also provided so consider that as well since it performs better in some conditions.
- Minimize use of Iframes as it's costly.
- Avoid try-catch blocks for control-flow as they perform poorly. Exceptions should be used only in truly exceptional situations.
- Minimize Cookie/CSS sizes.
- Minimize DOM objects on page as they are heavy weight.
- Use link tags rather than @import to use/link up CSS.
- Favicon, being a static image displayed in the browser’s address bar, should be cacheable and compressed.
- Always prefer a cache-friendly folder structure. For example, create specific folders for static contents, like /static for static images/static pages.
- SSL can never be cached so minimize its usage. Keep it for those pages which need to be secure, rather than using it for all the pages.
- HTTP Post requests can’t be cached, so choose the HTTP method appropriately.
- Prevent Denial of Service (Dos) attacks.
- Prevent SQL Injection.
- Prevent Cross Site Scripting (XSS).

Shared Cache - compare results between version 1.0.2.134 and 2.0.0.140 and upper
- Server is running as async TCP Server with a custom Threadpool
- Network traffic decreased dramatically between, especially upon server echos
- We take now full advantage of object pooling, so each action from the client in the test application gone use only 1 single "new Socket()" instead of several thousands.
240 - Add 10 objects with the size approx. of 100kb.
280 - Add 10 objects with the size approx. of 1MB.
As bigger the message (payload) which has to be transferred to the server, as better the results are getting. I was wondering if I have done a calculation mistake but I re-run the whole test 3 times.

Threaded Asynchronous Tcp Server with a blocking Client
I don't know now how many prototypes I have written in the past few weeks to verify which approach would fit best to scale and be most performance for indeXus.Net Shared Cache. To write a Client / Server Architecture which mostly will be N:M connectivity was not that easy as I thought in beginning.
Honestly I believe I have study every single C# sample I found on the common search engines and arrived to the point where I started to adapt the samples. Unfortunately 99% of founded samples are showing how to pass a string from the client to the server beside one blog which has written down a lot of theory and some very nice diagrams without to come up with code. I only can recommend you to read this blog up and down before you write even one single line of code: http://www.coversant.net/Coversant/Blogs/tabid/88/EntryID/10/Default.aspx. There are some very smart people around they have done great work.
After a while of research, I get to koders.com where I found a strip-down version of their product.
Another very useful page with a lot of sample code around .net is Mike Woodrings's .net Sample Page which contains a bunch of great examples for different domains.
I think I have tried any way to use Sockets now:
- Blocked Sockets
- Unblocked Sockets
- Poll Sockets
- Select
Every prototype I have done so far had his advantages and disadvantages. In the end of this post I will provide 2 downloads:
- prototype with poll sockets on client and server
- protptype with block sockets on client side and async server handling
Lets dive into different key parts of the client and the server. An additional issue I would like to mention here is that the whole code is 100% managed.
We gone start first with the server. As already mention the server is working Asynchronous which means we have to handle with IAsyncResult. Upon Server start we begin run the server within a different thread and the client cleanup will be handled by a TimerCallback to purge disconnected clients in case they not removed before upon disconnection.
ThreadStart serverListener = new ThreadStart(this.StartListening);
serverThread[0] = new Thread(serverListener);
serverThread[0].IsBackground = true;
serverThread[0].Start();
TimerCallback timerDelegate = new TimerCallback(this.CheckSockets);
this.lostTimer = new Timer(timerDelegate, null, SharedCacheTcpServer.timerTimeout, SharedCacheTcpServer.timeoutMinutes);
Since we have started now the serverListener we Bind the server IPEndPoint to the requested ip and port and start to listen for connections from clients. Once a connection is received it only will be destroyed in one of the following 2 cases:
- The Socket has not been used for a certain amount of time
- Client Socket get disconnected.
With this we avoid to much Server resources. As started we will use a ManualResetEvent to accept only one by one client. I have commented this part for testing purposes and the server started to throw memory exceptions. So keep it simple in the meaning, only start a new BeginAccept once you finished to move the client into AccecptCallback.
private void AccecptCallback(IAsyncResult ar)
{
// signal main thread to continue
this.allDone.Set();
Socket clientListener = ar.AsyncState as Socket;
if (clientListener != null)
{
Socket handler = clientListener.EndAccept(ar);
Console.WriteLine(@"Connected by client: {0}", handler.RemoteEndPoint);
StateObject state = new StateObject();
state.WorkSocket = handler;
state.AliveTimeStamp = DateTime.Now;
... and some more code ..
once you have done all setup for you StateObject (this is the object which contains all different data between the calls) we able to call BeginReceive. SharedCache Protocol between client and server keep simple: [messageLength][message] so if we are not able to get the whole message at once we have to call several times BeginReceive until we have received everything from the client and we able to run the custom stuff on the server.
Once we done with our reading we can start to process received package and process with it. To keep server resources (amount of threads) under control I decided to use Mike's Threadpool.
I think the 2 most important parts are within this message is to know that we need to read the header which indicates to message length and if we need to read more data for this message or do we can proceed it arrived data.
// check for header
if (state.ReadHeader) { .....
// check for message length -> TODO: how to check longer values as int count in list????
if (state.DataBuffer.ToArray().LongLength == state.MessageLength) { ...
as you can see there is even one open point since I use in my state object a List
int.MaxValue as maximal message length ;-)
the next key position in above code print screen is that we use at this place again handler.BeginReceive() since we want to client connection keep opened as long as possible. Some previous tests had shown me while i open and close 1000 Sockets the time reduction to use always the same is more then 50%. Before we can post the request into ThreadPool we need to remove the Range of our message size [8 bytes] that's why we do: state.DataBuffer.RemoveRange(0,8); once we have posted it to the threadpool to pool handles the message sending the Echo to the waiting client.
HandleClientMessage is the place which is called after you get the free Thread from the ThreadPool - here you can manage your Server side stuff and once you done you can send it back to the Client. If you work within Winform environment a more event driven design would be correct but for sharedcache this would not be correct since the client is waiting for the server response.
in the above example we do nothing else then to set an Attribute of the object IndexusMessage to Successful.
The response from the server needs to be prepared, then also the client waits for the same struct [message length][message data]. Therefore we call UtilByte.CreateMessageHeader(with the msg.GetBytes() which returns a byte array) and we combine both values to 1 single byte array. since this is done we can free up resources and set the actual messageLength on the state so we know how much data we need to send to the client which is not less important.
Within the Send() method we start the async call: socket.BeginSend() or if we do not have anything to send back (this case does not happen here) we reset all state data and start to receive again without to destroy the state and the socket which is included in the state. The
same idea happens within the SendCallback() we call BeginSend() as long we have data to send and once we sent everything to the client we reset the state and start to receive again with socket.BeginReceive().
These are all important parts on the server side, I will wrap up the client in a different post within the next few days.
The 2 best code-solution I have found on the web are the following 2 links:
http://www.codeproject.com/KB/IP/Generic_TCP_IP_server.aspx
http://www.codeproject.com/KB/IP/AsyncSocketServerandClien.aspx
Both of them could not handle the case I needed so I hope people can use the Prototypes in this or another way. It would be great if you let me know if you are using them. So here are the downloads:

Windows TCP Error Codes (Winsock Error Codes)
WSAEACCES
(10013)
Permission denied.
An attempt was made to access a socket in a way forbidden by its access permissions. An example is using a broadcast address for sendto without broadcast permission being set using setsockopt(SO_BROADCAST).
WSAEADDRINUSE
(10048)
Address already in use.
Only one usage of each socket address (protocol/IP address/port) is normally permitted. This error occurs if an application attempts to bind a socket to an IP address/port that has already been used for an existing socket, or a socket that wasn't closed properly, or one that is still in the process of closing. For server applications that need to bind multiple sockets to the same port number, consider using setsockopt(SO_REUSEADDR). Client applications usually need not call bind at all - connectwill choose an unused port automatically.
WSAEADDRNOTAVAIL
(10049)
Cannot assign requested address.
The requested address is not valid in its context. Normally results from an attempt to bind to an address that is not valid for the local machine, or connect/sendtoan address or port that is not valid for a remote machine (e.g. port 0).
WSAEAFNOSUPPORT
(10047)
Address family not supported by protocol family.
An address incompatible with the requested protocol was used. All sockets are created with an associated "address family" (i.e. AF_INET for Internet Protocols) and a generic protocol type (i.e. SOCK_STREAM). This error will be returned if an incorrect protocol is explicitly requested in the socket call, or if an address of the wrong family is used for a socket, e.g. in sendto.
WSAEALREADY
(10037)
Operation already in progress.
An operation was attempted on a non-blocking socket that already had an operation in progress - i.e. calling connecta second time on a non-blocking socket that is already connecting, or canceling an asynchronous request (WSAAsyncGetXbyY) that has already been canceled or completed.
WSAECONNABORTED
(10053)
Software caused connection abort.
An established connection was aborted by the software in your host machine, possibly due to a data transmission timeout or protocol error.
WSAECONNREFUSED
(10061)
Connection refused.
No connection could be made because the target machine actively refused it. This usually results from trying to connect to a service that is inactive on the foreign host - i.e. one with no server application running.
WSAECONNRESET
(10054)
Connection reset by peer.
A existing connection was forcibly closed by the remote host. This normally results if the peer application on the remote host is suddenly stopped, the host is rebooted, or the remote host used a "hard close" (see setsockopt for more information on the SO_LINGERoption on the remote socket.)
WSAEDESTADDRREQ
(10039)
Destination address required.
A required address was omitted from an operation on a socket. For example, this error will be returned if sendtois called with the remote address of ADDR_ANY.
WSAEFAULT
(10014)
Bad address.
The system detected an invalid pointer address in attempting to use a pointer argument of a call. This error occurs if an application passes an invalid pointer value, or if the length of the buffer is too small. For instance, if the length of an argument which is a struct sockaddr is smaller than sizeof(struct sockaddr).
WSAEHOSTDOWN
(10064)
Host is down.
A socket operation failed because the destination host was down. A socket operation encountered a dead host. Networking activity on the local host has not been initiated. These conditions are more likely to be indicated by the error WSAETIMEDOUT.
WSAEHOSTUNREACH
(10065)
No route to host.
A socket operation was attempted to an unreachable host. See WSAENETUNREACH
WSAEINPROGRESS
(10036)
Operation now in progress.
A blocking operation is currently executing. Windows Sockets only allows a single blocking operation to be outstanding per task (or thread), and if any other function call is made (whether or not it references that or any other socket) the function fails with the WSAEINPROGRESS error.
WSAEINTR
(10004)
Interrupted function call.
A blocking operation was interrupted by a call to WSACancelBlockingCall.
WSAEINVAL
(10022)
Invalid argument.
Some invalid argument was supplied (for example, specifying an invalid level to the setsockopt function). In some instances, it also refers to the current state of the socket - for instance, calling accept on a socket that is not listening.
WSAEISCONN
(10056)
Socket is already connected.
A connect request was made on an already connected socket. Some implementations also return this error if sendto is called on a connected SOCK_DGRAM socket (For SOCK_STREAM sockets, the to parameter in sendtois ignored), although other implementations treat this as a legal occurrence.
WSAEMFILE
(10024)
Too many open files.
Too many open sockets. Each implementation may have a maximum number of socket handles available, either globally, per process or per thread.
WSAEMSGSIZE
(10040)
Message too long.
A message sent on a datagram socket was larger than the internal message buffer or some other network limit, or the buffer used to receive a datagram into was smaller than the datagram itself.
WSAENETDOWN
(10050)
Network is down.
A socket operation encountered a dead network. This could indicate a serious failure of the network system (i.e. the protocol stack that the WinSock DLL runs over), the network interface, or the local network itself.
WSAENETRESET
(10052)
Network dropped connection on reset.
The host you were connected to crashed and rebooted. May also be returned by setsockoptif an attempt is made to set SO_KEEPALIVE on a connection that has already failed.
WSAENETUNREACH
(10051)
Network is unreachable.
A socket operation was attempted to an unreachable network. This usually means the local software knows no route to reach the remote host.
WSAENOBUFS
(10055)
No buffer space available.
An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full.
WSAENOPROTOOPT
(10042)
Bad protocol option.
An unknown, invalid or unsupported option or level was specified in a getsockopt or setsockoptcall.
WSAENOTCONN
(10057)
Socket is not connected.
A request to send or receive data was disallowed because the socket is not connected and (when sending on a datagram socket using sendto) no address was supplied. Any other type of operation might also return this error - for example, setsockoptsetting SO_KEEPALIVE if the connection has been reset.
WSAENOTSOCK
(10038)
Socket operation on non-socket.
An operation was attempted on something that is not a socket. Either the socket handle parameter did not reference a valid socket, or for select, a member of an fd_set was not valid.
WSAEOPNOTSUPP
(10045)
Operation not supported.
The attempted operation is not supported for the type of object referenced. Usually this occurs when a socket descriptor to a socket that cannot support this operation, for example, trying to accept a connection on a datagram socket.
WSAEPFNOSUPPORT
(10046)
Protocol family not supported.
The protocol family has not been configured into the system or no implementation for it exists. Has a slightly different meaning to WSAEAFNOSUPPORT, but is interchangeable in most cases, and all Windows Sockets functions that return one of these specify WSAEAFNOSUPPORT.
WSAEPROCLIM
(10067)
Too many processes.
A Windows Sockets implementation may have a limit on the number of applications that may use it simultaneously. WSAStartupmay fail with this error if the limit has been reached.
WSAEPROTONOSUPPORT
(10043)
Protocol not supported.
The requested protocol has not been configured into the system, or no implementation for it exists. For example, a socketcall requests a SOCK_DGRAM socket, but specifies a stream protocol.
WSAEPROTOTYPE
(10041)
Protocol wrong type for socket.
A protocol was specified in the socketfunction call that does not support the semantics of the socket type requested. For example, the ARPA Internet UDP protocol cannot be specified with a socket type of SOCK_STREAM.
WSAESHUTDOWN
(10058)
Cannot send after socket shutdown.
A request to send or receive data was disallowed because the socket had already been shut down in that direction with a previous shutdown call. By calling shutdowna partial close of a socket is requested, which is a signal that sending or receiving or both has been discontinued.
WSAESOCKTNOSUPPORT
(10044)
Socket type not supported.
The support for the specified socket type does not exist in this address family. For example, the optional type SOCK_RAW might be selected in a socketcall, and the implementation does not support SOCK_RAW sockets at all.
WSAETIMEDOUT
(10060)
Connection timed out.
A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
WSAEWOULDBLOCK
(10035)
Resource temporarily unavailable.
This error is returned from operations on non-blocking sockets that cannot be completed immediately, for example recv when no data is queued to be read from the socket. It is a non-fatal error, and the operation should be retried later. It is normal for WSAEWOULDBLOCK to be reported as the result from calling connecton a non-blocking SOCK_STREAM socket, since some time must elapse for the connection to be established.
WSAHOST_NOT_FOUND
(11001)
Host not found.
No such host is known. The name is not an official hostname or alias, or it cannot be found in the database(s) being queried. This error may also be returned for protocol and service queries, and means the specified name could not be found in the relevant database.
WSA_INVALID_HANDLE
(OS dependent)
Specified event object handle is invalid.
An application attempts to use an event object, but the specified handle is not valid.
WSA_INVALID_PARAMETER
(OS dependent)
One or more parameters are invalid.
An application used a Windows Sockets function which directly maps to a Win32 function. The Win32 function is indicating a problem with one or more parameters.
WSAINVALIDPROCTABLE
(OS dependent)
Invalid procedure table from service provider.
A service provider returned a bogus proc table to WS2_32.DLL. (Usually caused by one or more of the function pointers being NULL.)
WSAINVALIDPROVIDER
(OS dependent)
Invalid service provider version number.
A service provider returned a version number other than 2.0.
WSA_IO_PENDING
(OS dependent)
Overlapped operations will complete later.
The application has initiated an overlapped operation which cannot be completed immediately. A completion indication will be given at a later time when the operation has been completed.
WSA_IO_INCOMPLETE
(OS dependent)
Overlapped I/O event object not in signaled state.
The application has tried to determine the status of an overlapped operation which is not yet completed. Applications that use WSAWaitForMultipleEventsin a polling mode to determine when an overlapped operation has completed will get this error code until the operation is complete.
WSA_NOT_ENOUGH_MEMORY
(OS dependent)
Insufficient memory available.
An application used a Windows Sockets function which directly maps to a Win32 function. The Win32 function is indicating a lack of required memory resources.
WSANOTINITIALISED
(10093)
Successful WSAStartup not yet performed.
Either the application hasn't called WSAStartup, or WSAStartup failed. The application may be accessing a socket which the current active task does not own (i.e. trying to share a socket between tasks), or WSACleanuphas been called too many times.
WSANO_DATA
(11004)
Valid name, no data record of requested type.
The requested name is valid and was found in the database, but it does not have the correct associated data being resolved for. The usual example for this is a hostname -> address translation attempt (using gethostbyname or WSAAsyncGetHostByName) which uses the DNS (Domain Name Server), and an MX record is returned but no A record - indicating the host itself exists, but is not directly reachable.
WSANO_RECOVERY
(11003)
This is a non-recoverable error.
This indicates some sort of non-recoverable error occurred during a database lookup. This may be because the database files (e.g. BSD-compatible HOSTS, SERVICES or PROTOCOLS files) could not be found, or a DNS request was returned by the server with a severe error.
WSAPROVIDERFAILEDINIT
(OS dependent)
Unable to initialize a service provider.
Either a service provider's DLL could not be loaded (LoadLibrary failed) or the provider's WSPStartup/NSPStartupfunction failed.
WSASYSCALLFAILURE
(OS dependent)
System call failure.
Returned when a system call that should never fail does. For example, if a call to WaitForMultipleObjectsfails or one of the registry functions fails trying to manipulate theprotocol/namespace catalogs.
WSASYSNOTREADY
(10091)
Network subsystem is unavailable.
This error is returned by WSAStartup if the Windows Sockets implementation cannot function at this time because the underlying system it uses to provide network services is currently unavailable. Users should check:
that the WINSOCK.DLL file is in the current path,
that the WINSOCK.DLL file is from the same vendor as the underlying protocol stack. They cannot be mixed and matched (WinSock DLLs must be supplied by the same vendor that provided the underlying protocol stack).
that they are not trying to use more than one Windows Sockets implementation simultaneously. If there is more than one WINSOCK DLL on your system, be sure the first one in the path is appropriate for the network subsystem currently loaded.
the Windows Sockets implementation documentation to be sure all necessary components are currently installed and configured correctly.
WSATRY_AGAIN
(11002)
Non-authoritative host not found.
This is usually a temporary error during hostname resolution and means that the local server did not receive a response from an authoritative server. A retry at some time later may be successful.
WSAVERNOTSUPPORTED
(10092)
WINSOCK.DLL version out of range.
The current Windows Sockets implementation does not support the Windows Sockets specification version requested by the application. Check that no old WINSOCK.DLL files are being accessed, or contact the stack vendor to see if an updated WINSOCK.DLL exists.
WSAEDISCON
(10094)
Graceful shutdown in progress.
Returned by recv, WSARecvto indicate the remote party has initiated a graceful shutdown sequence.
WSA_OPERATION_ABORTED
(OS dependent)
Overlapped operation aborted.
An overlapped operation was canceled due to the closure of the socket, or the execution of the SIO_FLUSH command in WSAIoctl.
