Socket Error Operation Would Block


If src_addr is not NULL, and the underlying protocol provides the source address, this source address is filled in. The remote address is not a valid address (such as ADDR_ANY). (Error code 10049)The requested address is not valid in its context. This error code corresponds to the Windows Sockets error WSAEWOULDBLOCK. The Creation of InetLog Context failed.

A blocking Windows Sockets 1.1 call is in progress, or the service provider is still processing a callback function. (Error code 10036)A blocking operation is currently executing. The solution to this problem is called "non-blocking sockets". This error occurs if an application passes an invalid pointer value, or if the length of the buffer is too small. share|improve this answer answered Mar 19 '09 at 10:13 S.Lott 262k53370650 Now my question referring to your answer is: Is the second case you present possible when we have

(Error code 10055)An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full. However, the other end of the socket could close the connection prematurely, which may lead to this. The IsWritable property can be used to determine if data can be written to the socket.

  • Failed to save document....
  • The virtual circuit was terminated due to a time-out or other failure.
  • No more file descriptors are available. (Error code 10024)Too many open sockets.

The same restrictions do not apply to SOCK_STREAM sockets. If no messages are available at the socket, the receive calls wait for a message to arrive, unless the socket is nonblocking (see fcntl(2)), in which case the value -1 is The content you requested has been removed.

From my tests (and documentation) it results that when using send on a blocking socket I have 2 cases: all the data is sent an error is returned and nothing is Microsoft Internet Information Services Setup required administrator privileg...

In this case, the operation to close the socket will fail with this error if it cannot be completed immediately. I ask as I've just seen an issue in my production environment. Cannot load INETSTP.DLL. The remote host cannot be reached from this host at this time. (Error code 10065)A socket operation was attempted to an unreachable host.


If the connect() is still pending, you might check to see if the user has pressed a "abort" button, and if so, call close() to stop trying to connect. For local errors, no address is passed (this can be checked with the cmsg_len member of the cmsghdr). Ewouldblock A successful WSAStartup call must occur before using this function. (Error code 10093)Either the application has not called WSAStartup or WSAStartup failed. Setup cannot determine the remote machine's operation system type.

There are too many connected users. This could occur when associating an address (on Windows NT 4 SP4 or later), another application, service, or kernel mode driver is associated to the same address with exclusive access. This could indicate a serious failure of the network system (that is, the protocol stack that the Windows Sockets DLL runs over), the network interface, or the local network itself. So, to turn on non-blocking mode requires three steps: Call the fcntl() API to retrieve the socket descriptor's current flag settings into a local variable.

A blocking Windows Sockets 1.1 call was canceled through WSACancelBlockingCall. (Error code 10004)A blocking operation was interrupted by a call to WSACancelBlockingCall. It is a nonfatal error, and the operation should be retried later. Authoritative answer host not found. (Error code 11001)No such host is known. check over here The addrlen argument is int * in 4.x BSD, libc4 and libc5.

For example, the optional type SOCK_RAW might be selected when creating a socket, and the implementation does not support SOCK_RAW sockets at all. In fact, if you reach a point where you actually WANT to wait for data on a socket that was previously marked as "non-blocking", you could simulate a blocking recv() just The network subsystem has failed. (Error code 10050)A socket operation encountered a dead network.

The descriptor is not a socket. (Error code 10038)The operation was attempted on something that is not a socket.

When you issue a call to connect(), your program doesn't regain control until either the connection is made, or an error occurs. The network subsystem has failed.
