Winsock Error In Recv


However, some WinSocks fail with WSAEINVAL you call connect() a second time (or subsequent) on a non-blocking socket. However, it is interchangeable in most cases, and all Windows Sockets functions that return one of these messages also specify WSAEAFNOSUPPORT. These resources can help you build awareness and prepare for defense. Return code/valueDescription WSA_INVALID_HANDLE 6 Specified event object handle is invalid. Source

The application has initiated an overlapped operation that cannot be completed immediately. Also, if MSG_WAITALL is specified along with MSG_OOB, MSG_PEEK, or MSG_PARTIAL, then this call will fail with WSAEOPNOTSUPP.

Browse other questions tagged c++ sockets tcp recv or ask your own question. The usual example for this is a host name-to-address translation attempt (using gethostbyname or WSAAsyncGetHostByName) which uses the DNS (Domain Name Server). You could use this to verify that you're receiving TCP resets or ICMP Port Unreachable packets each time you attempt to connect. If the response is using HTTP 1.1, and if the Connection header does not say close, then the server left the connection open on its end, and you can reuse the

  1. The FormatMessage function can be used to obtain the message string for the returned error.
  2. after failed calls to inet_addr() or gethostbyname()), then simply test your address value for zero before you pass it to sendto().
  3. We appreciate your feedback.
  4. WinSock functions: WSAEACCES (10013) Permission denied.
  5. Apparently, the Windows Sockets specification left this out by oversight.
  6. WSAEMSGSIZE 10040 Message too long.

It can occur if you're trying to run too many applications (of any kind) simultaneously on your machine. WinSock functions: send(), sendto() Additional functions: setsockopt() and any function that takes a socket (or file handle) as an input parameter. User suggestions: This error indicates a shortage of resources on your system. Recv Timeout We suggest local configuration changes that might remedy the problem, and network and server conditions that might be the cause.

WinSock functions: socket() See also: WSAESOCKTNOSUPPORT WSAEPROTOTYPE (10041) Protocol wrong type for socket. Two functions that are conspicuously absent from the current function list above are shutdown() and close socket(). The socket is marked as non-blocking (non-blocking operation mode), and the requested operation is not complete at this time. Why does Wolfram Alpha say the roots of a cubic involve square roots of negative numbers, when all three roots are real?

You can monitor available memory with Program Manager's "Help/About..." command. http://stackoverflow.com/questions/30028754/10038-wsa-socket-error-recv Either the socket handle parameter did not reference a valid socket, or for select, a member of an fd_set was not valid. Recv C++ WinSock functions: WSAEWOULDBLOCK (10035) Resource temporarily unavailable. Recv Example On a datastream socket, some applications use this error with a non-blocking socket calling connect() to detect when a connection attempt has completed, although this is not recommended since some WinSocks

It does not connect yet. @param strIPAddress: IP Adress to reach nPort: Port to connect to hSocket: client Socket if SERVER mode nTcpMode: mode for this connexion SERVER(1) or CLIENT(2) @return this contact form These are obviously related in some way but I am still confused as in how. I was not understanding that if I created a socket connection on the client, that I could close it on the server using closesocket(). For instance, you might get WSAEBADF in place of WSAENOTSOCK on a system that provides some socket and file handle equivalency. Recv Vs Read

WSAEINVALIDPROVIDER 10105 Service provider is invalid. WSAEINTR (10004) Interrupted function call. Do a traceroute to try to determine where the failure occurs along the route between your host and the destination host. have a peek here You can verify that the remote system is rejecting your connection attempt by checking the network statistics locally.

The system detected an invalid pointer address in attempting to use a pointer argument of a call. Recv Msg_peek WSAEMSGSIZE The message was too large to fit into the specified buffer and was truncated. User suggestions: It may indicate that there are too many WinSock applications running simultaneously, but this is unlikely since most network systems have many socket handles available.

The Error is WSAECONNRESET (10054) Connection reset by peer.

Note: this error may also result if you are trying to send a multicast packet and the default gateway does not support multicast (check your interface configuration). Alternately, you can get the local IP address by calling gethostname() followed by gethostbyname(). Developer suggestions: Every application that uses non-blocking sockets must be prepared for this error on any call to the functions mentioned below.

Cannot remove a directory that is not empty. Use socket state in an application and/or handle this error gracefully as a non-fatal error.

Issuing another blocking Winsock call inside an APC that interrupted an ongoing blocking Winsock call on the same thread will lead to undefined behavior, and must never be attempted by Winsock Some invalid argument was supplied (for example, specifying an invalid level to the setsockopt function). Yes No Additional feedback? 1500 characters remaining Submit Skip this Thank you! Handle the request as a non-fatal error (if possible), since some WinSock's can legally fail the request.

WinSock description: The Windows Sockets definition of this error is very different from Berkeley. On a datastream socket, the connection was reset. WSAESTALE 10070 Stale file handle reference. Yes No Additional feedback? 1500 characters remaining Submit Skip this Thank you!

So, for example, you can expect this error if a WinSock implementation doesn't support socket type SOCK_RAW within the Internet address family (AF_INET). If you used a hostname, did it resolve to the correct address? A protocol was specified in the socket function call that does not support the semantics of the socket type requested. The requested address is not valid in its context.

A Windows Sockets implementation may have a limit on the number of applications that can use it simultaneously. Each implementation may have a maximum number of socket handles available, either globally, per process, or per thread.
