Winsock Wsa Error Codes


WSAECONNABORTED 10053 Software caused connection abort. For instance, even if you request to send() a few bytes of data on a newly created TCP connection, send() could fail with WSAEWOULDBLOCK (if, say, the network system has a I encountered a strange problem when trying to accept clients, I have a loop that looks like this. The only time a WinSock might use this error--at least with a TCP/IP implementation of WinSock--it fails a function with other errors (for example, WSAETIMEDOUT). his comment is here

connect(), send(), recv(), et cetera). share|improve this answer answered May 10 '13 at 8:35 Remy Lebeau 234k13144273 Thanks! Detailed description: There's at least one WinSock implementation that will occasionally fail a function and report this as the error value, even though the function succeeded. Join them; it only takes a minute: Sign up How do I retrieve an error string from WSAGetLastError()?

Socket Error 10054

In Linux, I could use strerror() to convert an errno code into a human-readable string. Since the buffering requirements for sending are less than for receiving datagrams, it's conceivable that you can send a datagram larger than you can receive. WinSock description: Same as Berkeley for host resolution. This error occurs when the sin_port value is zero in a sockaddr_in structure for connect() or sendto().

The FormatMessage function can be used to obtain the message string for the returned error. A getsockopt function when called with an optname parameter of SO_ERROR also resets the extended error code to zero. Check whether you have a router configured in your network system (your WinSock implementation). Socket Error 10054 Connection Reset By Peer WinSock functions: recv(), recvfrom(), send(), sendto() WSAENAMETOOLONG (10063) File name too long.

User suggestions: see WSAENETUNREACH for details WinSock functions: Additional functions: Any function that does network I/O. Socket Error Codes Linux If you're on a serial connection, your local router is the IP address of the host you initially logged onto with SLIP or PPP. That means that on 32-bit systems, the addresses have to be multiples of 4, and on 64-bit systems, they must be multiples of 8. Developer suggestion: The simple suggestion is "don't do that." No matter what value you use for the "how" parameter to the shutdown() function, you cannot send afterwards.

a long zero) in the sockaddr_in structure passed to sendto(). Socket Error 11004 I have found theses on a similar subject to my own, and want to use their references with my own text and a similar flow. An invalid value was given for one of the arguments to a function. The v1.1 specification also lists connect(), although it does not allocate a descriptor.

  1. Check the destination address itself; is it the one you wanted to go to?
  2. For more information on debugging problems, see Chapter 13, "Debugging." Errorless Functions Eight of the forty-six functions in the Windows Sockets API are not referenced in any of the "WinSock function"
  3. An application attempted an input/output network function call before establishing an association with a remote socket (i.e.

Socket Error Codes Linux

TCP/IP scenario: Calling shutdown() with how=1 or how=2 sends a TCP FIN packet to the remote address, which literally means "I'm done sending." If the local host sent any more data http://www.sockets.com/err_lst1.htm This error apparently also takes the place of WSAEPFNOSUPPORT (which means "protocol family not supported"), since that error is not listed for socket() in the v1.1 WinSock specification. Socket Error 10054 In this case, the WSAEBADF error might mean the same as a WSAENOTSOCK error. Socket Error 10053 WinSock functions: WSAEUSERS (10068) Too many users.

WinSock functions: WSAENETDOWN (10050) Network is down. this content WinSock functions: See also: WSAECONNABORTED, WSAECONNRESET, WSAENETRESET, WSAETIMEDOUT WSAEHOSTUNREACH (10065) No route to host. If we modify our Winsock initialization code slightly... Yes No Additional feedback? 1500 characters remaining Submit Skip this Thank you! Socket Error 10049

If it persists, exit Windows or reboot your machine to remedy the problem. Generically, the error means the network system has run out of socket handles. WinSock description: The current WinSock implementation does not support the Windows Sockets specification version requested by the application. weblink Check that your network system (WinSock implementation) has a utility that shows network statistics.

Typically their descriptions are similar. Wsagetlasterror 10054 This documentation is archived and is not being maintained. In fact, on occasion you can benefit if the WinSock implementation returns these other errors.

If you don't have the proper subnet mask, your network system may treat a local address as a remote address (so it forwards addresses on the local subnet to the router,

On the server end, you could use a network system utility similar to BSD's "netstat -a" command to check that your server is running, and listening on the right port number. WSAEISCONN (10056) Socket is already connected. The standard meaning for WSAEINVAL applies to connect() (invalid argument). Wsagetlasterror 0 Berkeley description: A socket operation encountered a dead network.

However, they don't need to set the WinSock error value, because there's only one reason for their failure: the input parameter was invalid. When a particular Windows Sockets function indicates an error has occurred, this function should be called immediately to retrieve the extended error code for the failing function call. Handle the request as a non-fatal error (if possible), since some WinSock's can legally fail the request. check over here Berkeley description: A directory with entries other than `.'and `..' was supplied to a remove directory or rename call.

This means, the version we are trying to use doesn't exist. recv(), recvfrom(), send(), sendto(): MSG_OOB was specified, but the socket is not of type SOCK_STREAM Developer suggestions: don't do that. Securing a LAN that has multiple exposed external Cat 6 cable runs? Check the destination address you are using.

Specifically, the v1.1 Windows Sockets specification notes the domain name system (DNS) errors "FORMERR, REFUSED, and & NOTIMP.
