In this case, the 2nd application will fail with WSAEADDRINUSE. This error occurs if an application passes an invalid pointer value, or if the length of the buffer is too small. This will verify that the destination network is functioning. TCP/IP scenario: In BSD-compatible implementations, the local network system generates this error if there isn't a default route configured. have a peek here
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. A completion indication will be given later when the operation has been completed.Send dataThis operation sends data on a connected socket or to a specific destinationPossible ErrorsThe connection has been dropped, WSAEHOSTDOWN 10064 Host is down. Handle the request as a non-fatal error (if possible), since some WinSock's can legally fail the request.
The connection has been dropped because of a network failure or because the peer system failed to respond. (Error code 10060)A connection attempt failed because the connected party did not properly Berkeley description: A protocol was specified that does not support the semantics of the socket type requested. 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. WSAENETUNREACH 10051 Network is unreachable.
Typically, only one usage of each socket address (protocol/IP address/port) is permitted. The network subsystem has failed. (Error code 10050)A socket operation encountered a dead network. WSANO_RECOVERY 11003 This is a nonrecoverable error. Socket Error 10053 This error may also result if a connection was broken due to keep-alive activity detecting a failure while one or more operations are in progress.
A retry at some time later may be successful. Not implemented: name server does not perform specified operation. No connection could be made because the target computer actively refused it. WSAEREFUSED 10112 Database query was refused.
For example, you shouldn't necessarily expect to be able to use NS addresses with ARPA Internet protocols. Socket Error 10049 Berkeley description: An operation was attempted on something that is not a socket. WSAEPROTONOSUPPORT (10043) Protocol not supported. No buffer space is available. (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.
The application should close the socket as it is no longer usable. For inet_addr(), this could mean the content of the buffer passed or the buffer itself is invalid. Socket Error 10038 The requested protocol has not been configured into the system, or no implementation for it exists. What Is A Socket Error In fact, on occasion you can benefit if the WinSock implementation returns these other errors.
The socket input parameter is not a valid socket handle (either it never was valid, it's a file handle (not a socket handle), or if it was a socket handle, it navigate here The Windows Sockets API does not have analogs for the Berkeley perror() and herror() functions that take the error value as input, and output the (short) text of each error value share|improve this answer answered May 23 '10 at 13:25 avakar 23.3k44790 Thanks for the help! notice the m_ its a member variable of the instance each thread works on a separated instance. Socket Error 10054 Connection Reset By Peer
An invalid or inconsistent flowspec was found in the QoS provider-specific buffer. The message was too large to fit into the specified buffer and was truncated. (Error code 10040)If the datagram or message is larger than the buffer specified, the buffer is filled This is not a soft error, another type of name server request may be successful. Check This Out Although it is olny for four people.I think I fixed all the problems, although it's actually a completly different program now.#include
Specifically, v1.1 WinSock spec notes that this error occurs if the length of the buffer is too small. Socket Error 11004 But that's not to say you shouldn't still be prepared. WinSock functions: accept(), bind(), closesocket(), connect(), gethostbyaddr(), gethostbyname(), gethostname(), getpeername(), getprotobyname(), getprotobynumber(), getservbyname(), getservbyport(), getsockname(), getsockopt(), ioctlsocket(), listen(), recv(), recvfrom(), select(), send(), sendto(), setsockopt(), shutdown(), socket(), WSAAsyncGetHostByAddr(), WSAAsyncGetHostByName(), WSAAsyncGetProtoByName(), WSAAsyncGetProtoByNumber(), WSAAsyncGetServByName(),
WSAEINVALIDPROCTABLE 10104 Procedure call table is invalid. The remote address is not a valid address (such as ADDR_ANY). (Error code 10049)The requested address is not valid in its context. By calling shutdown a partial close of a socket is requested, which is a signal that sending or receiving, or both have been discontinued. Windows 10 Socket Error Exporting an animation as a gif file Was Donald Trump's father a member of the KKK?
This operation may fail with this error if the limit has been reached. The network subsystem or the associated service provider has failed. (Error code 10050)A socket operation encountered a dead network. Here is a useable macro: #define MAKEWORD(low, high) ((WORD)(((BYTE)(low)) | (((WORD)((BYTE)(high))) << 8))) WinSock functions: WSAStartup(). [Go to Top] Errors in Numerical Order WSABASEERR (0) No Error WSAEINTR (10004) Interrupted system this contact form You cannot use more than one WinSock implementation simultaneously.
Windows Sockets only allows a single blocking operation—per- task or thread—to be outstanding, and if any other function call is made (whether or not it references that or any other socket) WSA_QOS_EFILTERTYPE 11020 Invalid QoS filter type. What are the holes on the sides of a computer case frame for? A blocking Windows Sockets 1.1 call was canceled through WSACancelBlockingCall. (Error code 10004)A blocking operation was interrupted by a call to WSACancelBlockingCall.
Some of these neglected error values are among those mentioned earlier that provide "finer resolution" on different WinSock implementations. Additional functions: With a datagram socket: send() or sendto(), or FD_READ.

A blocking operation was interrupted by a call to WSACancelBlockingCall. WinSock description: Same as Berkeley.
Started by Azjherben, Aug 11 2009 06:51 AM Old topic! No process may have more than a system-defined number of file descriptors open at a time. Although some WinSock implementations might not issue other errors if a connection fails, so you can handle this error as you would others that indicate connection failure. Either the socket handle parameter did not reference a valid socket, or for select, a member of an fd_set was not valid.
