The error code of the last failed socket call on this thread: WSAGetLastError on Windows, errno on Unix.
Read it straight after the call that failed. Compare it with SOCKET_WOULDBLOCK, SOCKET_WOULDBLOCK_CONNECT or the
WSAE... constants.
get_last_socket_error :: () -> W.OS_Error_CodeThe error code of the last failed socket call on this thread: WSAGetLastError on Windows, errno on Unix.
Read it straight after the call that failed. Compare it with SOCKET_WOULDBLOCK, SOCKET_WOULDBLOCK_CONNECT or the
WSAE... constants.
Returns
- W.OS_Error_Code
get_last_socket_error :: () -> P.OS_Error_CodeThe error code of the last failed socket call on this thread: errno on Unix, WSAGetLastError on Windows.
Read it straight after the call that failed, before any other call can replace it. Compare it with SOCKET_WOULDBLOCK,
SOCKET_WOULDBLOCK_CONNECT or the platform's own error constants.
Returns
- P.OS_Error_Code
