Some error codes defined in the Winsock2.h header file are not returned from any function. Typically, though, WinSock generates this error when it receives a "host unreachable" ICMP message from a router. Note that this error is returned by the operating system, so the error number may change in future releases of Windows. WSAEADDRNOTAVAIL 10049 Cannot assign requested address.

Whether to handle it as a fatal error or non-fatal error depends on the application and the context, so it's entirely up to you to decide.
WSAGetLastError() and WSAIsBlocking() cannot fail. WSAECONNRESET 10054 Connection reset by peer. the math behind the sequence 0,1,153,370,371,407 How do I express the position of an object by counting from the last? For instance, you might get WSAEBADF in place of WSAENOTSOCK on a system that provides some socket and file handle equivalency.
An invalid or inconsistent flowspec was found in the QOS structure. One thing that seems dodgy to me is hard-casting the SOCKET m_oSocket to sockaddr, but this seems to be normal practice for Winsock programming when I've been reading examples. Berkeley description: A write to an ordinary file, the creation of a directory or symbolic link, or the creation of a directory entry failed because the user's quota of disk blocks Socket Error 10054 Connection Reset By Peer Specifically, v1.1 WinSock spec notes that this error occurs if the length of the buffer is too small.
For protocols and services resolution, it means the respective database wasn't located. What Is A Socket Error WSA_QOS_EFLOWSPEC 11017 QoS flowspec error. WSAENOBUFS 10055 No buffer space available. I've read everything you posted to me but without any success - still the same problem: WSAEADDRNOTAVAIL - Error 10049 My code seems to be exactly the same according to the
WinSock description: Same as Berkeley. Socket Error Codes Linux WSAEINTR 10004 Interrupted function call. WinSock functions: recv(), recvfrom(), send(), sendto() WSAENAMETOOLONG (10063) File name too long. For instance, this error will occur if you try to run two applications that have FTP servers.
Berkeley description: A message sent on a socket was larger than the internal message buffer or some other network limit. 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). Socket Error 10054 WSAESHUTDOWN 10058 Cannot send after socket shutdown. Socket Error 10053 Which word wasn't with Wednesday's ...crossword how to make bc to show me 10 and not 10.00 Is it poor technique or physiology that causes people to cycle with their knees
WSA_OPERATION_ABORTED 995 Overlapped operation aborted. Status of four varnas created by God Should the sole user of a *nix system have two accounts? No more results can be returned by the WSALookupServiceNext function. WinSock functions: socket() See also: WSAEAFNOSUPPORT, WSAEPFNOSUPPORT WSAEREMOTE (10071) Too many levels of remote in path Berkeley description: Item is not local to the host. Socket Error 10049
This normally results from an attempt to bind to an address that is not valid for the local computer. This error is returned if an incorrect protocol is explicitly requested in the socket call, or if an address of the wrong family is used for a socket, for example, in Use socket state in an application and/or handle this error gracefully as a non-fatal error. Detailed descriptions: the specific meanings that some WinSock functions have for some errors.
How can I build a board to mount climbing holds in my house? Socket Error 10061 Connection Refused 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 Check the destination address you are using.
The sockets API has a shortcut for that, which is shorter and hides some of the internal implementation details. Berkeley description: This is a temporary condition and later calls to the same routine may complete normally (also known as EAGAIN error in Berkeley Software Distribution version 4.3) WinSock description: Same An unknown or conflicting QoS style was encountered. Socket Error 11001 WSA_QOS_POLICY_FAILURE 11011 QoS policy failure.
WSAENOPROTOOPT (10042) Bad protocol option. If you want to send out a broadcast message, you bind() to the adapter that is going to send the broadcast, and then sendto() the broadcast IP. A call to the WSALookupServiceEnd function was made while this call was still processing. User suggestions: Things an application user can do to diagnose the error condition further, and/or remedy it.
send() & sendto(): socket not bound (for Dgram) or not yet connected (for Stream) The v1.1 specification also has a detailed description for the connect() function which says: "socket not already Every error description contains at least: Summary Info: Error macro: manifest constant, as defined in WINSOCK.H Error value: as defined in v1.1 WINSOCK.H Short description Berkeley description: text describing the equivalent WSAECONNRESET (10054) Connection reset by peer. Note the British spelling (with an 'S' instead of a 'Z').
An application used a Windows Sockets function that directly maps to a Windows function. Planning US Tourist Visa overstay; is this a bad idea? Berkeley description: No connection could be made because the target machine actively refused it. Developer suggestions: Assume bind() will fail with this error.
