Thirteen errors have "" next to the list of WinSock functions that can produce them. Although most of this appendix is for application developers, the User suggestions contain information that end-users and application support personnel might also find useful when an application fails. WSAVERNOTSUPPORTED 10092 Winsock.dll version out of range. Among other things, that is exactly what we've done here. have a peek at this web-site

We appreciate your feedback. If you have more than one WINSOCK DLL on your system, be sure the first one in the path is appropriate for the network subsystem currently loaded. If this tends to occur after running certain applications for a while, it might be a symptom of an application that doesn't return system resources (like memory) properly. Developer suggestion: Use the sample code fragment in the WSAStartup() documentation in the v1.1 specification, which demonstrates how an application negotiates a Windows Sockets specification version.

all other functions: retry the operation again later since it cannot be satisfied at this time. WinSock functions: WSAEFAULT (10014) Bad address. The Windows Sockets API provides access to "low-level" API's (like the transport protocols TCP and UDP), so this error is not relevant to WinSock. The server application might need to call htons() to translate the port to network byte order in the sockaddr structure.

Either the socket handle parameter did not reference a valid socket, or for select, a member of an fd_set was not valid. WinSock description: Same as Berkeley. host = gethostbyname(hst.c_str()); if(!host) { Print("%s", "Could not resolve the hostname."); int error = WSAGetLastError(); return "failed"; } } It seems I'm returning "failed" quite frequently. Socket Error 11004 We don't support this API version.

The current Windows Sockets implementation does not support the Windows Sockets specification version requested by the application. Berkeley description: A socket operation failed because the destination host was down. WSAENETUNREACH 10051 Network is unreachable. https://msdn.microsoft.com/en-us/library/aa450263.aspx WSA_QOS_EUNKOWNPSOBJ 11024 Unrecognized QoS object.

In this case, the 2nd application will fail with WSAEADDRINUSE. Winsock Error 10054 Fix 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. you're trying to share a socket between tasks). An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full.

Socket Error 10054 Connection Reset By Peer

Note the British spelling (with an 'S' instead of a 'Z'). Bonuses Berkeley description: The system detected an invalid address in attempting to use an argument of a call. Socket Error Codes Linux WSAENETDOWN 10050 Network is down. Socket Error 10053 Typically their descriptions are similar.

WinSock description: Similar to Berkeley & Microsoft C, the generic meaning is that an application passed invalid input parameter in a function call. http://nbxcorp.com/socket-error/winsock2-error-codes.html For protocol and services resolution, the name or number was not found in the respective database. 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 It can occur if you're trying to run too many applications (of any kind) simultaneously on your machine. Socket Error 10049

  • WinSock description: The WinSock implementation cannot function at this time, because the underlying system it uses to provide network services is currently unavailable.
  • WSAEADDRINUSE (10048) Address already in use.
  • WinSock description: Same as Berkeley, and then some.
  • WSAENETRESET 10052 Network dropped connection on reset.
  • Berkeley description: An attempt was made to access an open file (on an NFS filesystem) which is now unavailable as referenced by the file descriptor.
  • Berkeley description: A component of a path name exceeded 255 (MAXNAMELEN) characters, or an entire path name exceeded 1023 (MAXPATHLEN-1) characters.
  • Berkeley description: No connection could be made because the target machine actively refused it.
  • This is one of the most frequent errors and one of the best to encounter, since it's one of the least ambiguous.
  • 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

WinSock functions: recv(), recvfrom(), send(), sendto(), with datastream sockets only. However, it is interchangeable in most cases, and all Windows Sockets functions that return one of these messages also specify WSAEAFNOSUPPORT. Am I interrupting my husband's parenting? Source The Windows Sockets implementation documentation to be sure all necessary components are currently installed and configured correctly. 10092WSAVERNOTSUPPORTEDWinsock.dll version out of range.

When bind is called with a wildcard address (involving ADDR_ANY), a WSAEADDRINUSE error could be delayed until the specific address is committed. Windows Socket Error Windows 10 The connection has been broken due to keep-alive activity detecting a failure while the operation was in progress. Typically, though, WinSock generates this error when it receives a "host unreachable" ICMP message from a router.

you tried to connect to the wrong destination host address the server application isn't running on the destination host the server application isn't listening on the right port.

An existing connection was forcibly closed by the remote host. The requested name is valid and was found in the database, but it does not have the correct associated data being resolved for. WSAEPROTONOSUPPORT 10043 Protocol not supported. Winsock Error Windows 7 However, the WSAEPROTONOSUPPORT is another possible equivalent for WinSock to use in place of this error.

Unfortunately, to find out what these errors mean you need to contact that WinSock provider. Developer suggestions: Every application that uses non-blocking sockets must be prepared for this error on any call to the functions mentioned below. A QoS error occurred due to lack of resources. have a peek here WSAEBADF 10009 Bad file number.

They signal unusual error conditions for which there's no WinSock error equivalent. How much more than my mortgage should I charge for rent? 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 The protocol family has not been configured into the system or no implementation for it exists.

Berkeley description: An asynchronous signal (such as SIGINTor SIGQUIT) was caught by the process during the execution of an interruptible function. What's in Naboo's core, liquid water or plasma?

This usually means the local software knows no route to reach the remote host. 10052WSAENETRESETNetwork dropped connection on reset. WinSock description: Same as Berkeley. Alternately, you can get the local IP address by calling gethostname() followed by gethostbyname(). WSAENOBUFS 10055 No buffer space available.
