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. WSA_IO_INCOMPLETE 996 Overlapped I/O event object not in signaled state. WinSock functions: accept(), bind(), connect(), listen(), send(), sendto(), socket(), WSAAsyncGetHostByAddr(), WSAAsyncGetHostByName(), WSAAsyncGetProtoByName(), WSAAsyncGetProtoByNumber(), WSAAsyncGetServByName(), WSAAsyncGetServByPort(), FD_CONNECT Additional functions: Any other functions that use network system buffer space, like the "database functions", WSAEACCES 10013 Permission denied. have a peek here

However, there's little distinction between WSAEALREADY and WSAEINVAL since a WinSock DLL cannot tell the difference between an asynchronous operation that has been cancelled and one that was never valid. This error is returned if either a service provider's DLL could not be loaded (LoadLibrary failed) or the provider's WSPStartup or NSPStartup function failed. WSAVERNOTSUPPORTED 10092 Winsock.dll version out of range. Return value The return value indicates the error code for this thread's last Windows Sockets operation that failed. https://msdn.microsoft.com/en-us/library/windows/desktop/ms740668(v=vs.85).aspx

Remarks The WSAGetLastError function returns the last error that occurred for the calling thread. Each implementation may have a maximum number of socket handles available, either globally, per process or per thread. that they are not trying to use more than one Windows Sockets implementation simultaneously. 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.

  1. WSA_QOS_EUNKOWNPSOBJ 11024 Unrecognized QoS object.
  2. send() and sendto(): you cannot send a datagram as large as you've requested.
  3. An operation was attempted on a nonblocking socket with an operation already in progress—that is, calling connect a second time on a nonblocking socket that is already connecting, or canceling an
  4. WSAEHOSTDOWN (10064) Host is down. A socket operation failed because the destination host was down.
  5. Check your subnet mask.
  6. User suggestions: Don't try running two of the same types of server applications on the same machine.

This is necessary because some functions may reset the last extended error code to 0 if they succeed, overwriting the extended error code returned by a previously failed function. WinSock functions: listen(), FD_CONNECT Additional functions: connect(), sendto() WSAELOOP (10062) Too many levels of symbolic links. 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. Socket Error 10049 you didn't call setsockopt(SO_BROADCAST)).

Berkeley description: A connect or send request failed because the connected party did not properly respond after a period of time. (The timeout period is dependent on the communication protocol.) WinSock Socket Error 10054 Connection Reset By Peer WSAEUSERS 10068 Too many users. 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(), The v1.1 WinSock specification only ascribes thirty-three of the fifty errors to any of the WinSock functions in the v1.1 for Windows Sockets specification.

This error is returned by the WSCGetProviderInfo and WSCGetProviderInfo32 functions if the protocol entry specified could not be found. Socket Error 11004 Are 14 and 21 the only "interesting" numbers? 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 the byte-order functions, htonl(), htons(), ntohl and ntohl(), cannot fail.

The QoS reserve request has been confirmed. http://stackoverflow.com/questions/3400922/how-do-i-retrieve-an-error-string-from-wsagetlasterror WSA_IO_PENDING 997 Overlapped operations will complete later. Socket Error Codes Linux WSAEPROTOTYPE 10041 Protocol wrong type for socket. Windows Socket Error Windows 10 before calling connect() or accept()).

port 0). navigate here 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. We appreciate your feedback. 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. Socket Error 10053

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). Users should check: That the appropriate Windows Sockets DLL file is in the current path. The "address" they refer to, typically refers to the local "socket name", which is made up of the 3-tuple: protocol, port-number and IP address. http://devstude.net/socket-error/windows-socket-error-value.php Mais Windows ne positionne pas errno !

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 Winsock Error Windows 7 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. WinSock description: Same as Berkeley.

For information, see the Handling Winsock Errors topic.

it may occur when a pointer to a structures is invalid or when a value in structure field is invalid). It also has a specific meaning for setsockopt(). This is usually a temporary error during host name resolution and means that the local server did not receive a response from an authoritative server. Winsock Error 10054 Fix Check that your network system (WinSock implementation) has a utility that shows network statistics.

Berkeley description: A file descriptor argument was out of range, referred to no open file, or a read (write) request was made to a file that was only open for writing Berkeley description: The protocol family has not been configured into the system or no implementation for it exists. Developer suggestion: are you trying to use an optional feature? http://devstude.net/socket-error/windows-7-socket-error-10048.php This is usually caused by one or more of the function pointers being NULL.

Developer suggestions: Did you close a socket inadvertently in one part of an application without keeping another part notified? How would I translate “I slipped him a twenty” into German? Are you using an optional level or socket option that may not be supported on all WinSock implementations? For example, the error can occur when an attempt is made to read from a file that is not open, to open an existing read-only file for writing, or to open

Too many links were encountered in translating a pathname. WSASYSNOTREADY 10091 Network subsystem is unavailable. WinSock description: No equivalent. The socket is marked as non-blocking (non-blocking operation mode), and the requested operation is not complete at this time.

a long zero) in the sockaddr_in structure passed to sendto(). As we pointed out earlier, your application should be ready to encounter any error at any time. WSAEAFNOSUPPORT (10047) Address family not supported by protocol family. Developer suggestions: Chances are, that if you encounter this error, your application ignored the failure of some previous function.
