Winsock Error Code 10049

Contents

Some of these neglected error values are among those mentioned earlier that provide "finer resolution" on different WinSock implementations. WinSock description: Same as Berkeley for host resolution. But most of these function-less errors are simply out of place; they are inappropriate to the Windows Sockets API as it exists in the v1.1 specification. Esker" mean? http://nbxcorp.com/socket-error/winsock-error-10049.html

inet_addr(bindaddr) : INADDR_ANY; struct sockaddr_in localaddr; memset(&localaddr, 0, sizeof(struct sockaddr_in)); localaddr.sin_family = AF_INET; localaddr.sin_port = htons(port); // ERROR HERE! WinSock description: No equivalent.

Socket Error 10054

Winsock functions: bind(), connect(), listen(), FD_CONNECT WSAEADDRNOTAVAIL (10049) Cannot assign requested address. Try a traceroute to the destination address to check that all the routers are functioning. closesocket(): occurs on a non-blocking socket with non-zero timeout set with setsockopt() SO_LINGER. Be aware that without Javascript, this website may not behave as expected.

  1. 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.
  2. Some error codes defined in the Winsock2.h header file are not returned from any function.
  3. An unknown, invalid or unsupported option or level was specified in a getsockopt or setsockopt call.
  4. C++11 - typeid uniqueness Why does my choice of typeface ruin the user experience?
  5. User suggestions: Don't try running two of the same types of server applications on the same machine.
  6. WinSock description: Similar to Berkeley & Microsoft C, but in reference to sockets rather than file handles (although the descriptions in the v1.1 specification say "no more file descriptors available").
  7. If so, treat this as a non-fatal error and ignore it, if possible.
  8. Unfortunately, to find out what these errors mean you need to contact that WinSock provider.
  9. A general QoS error.

WinSock functions: send(), sendto(), setsockopt() Additional functions: Any function that does network I/O: recv(), recvfrom(), FD_READ, FD_WRITE See also: WSAECONNABORTED, WSAECONNRESET, WSAETIMEDOUT WSAENETUNREACH (10051) Network is unreachable. WinSock functions: Additional functions: any function that takes a socket (or file handle) as an input parameter See also: WSAENOTSOCK WSAECONNABORTED (10053) Software caused connection abort. It is a nonfatal error, and the operation should be retried later. Socket Error 11004 WSAEPFNOSUPPORT 10046 Protocol family not supported.

WinSock description: Same as Berkeley; the option is unknown or unsupported. WSASERVICE_NOT_FOUND 10108 Service not found. You can attempt to avoid the error by calling WSAIsBlocking() before making any WinSock function calls. For WinSock, this error is equivalent to Berkeley's EHOSTUNREACH error, the catch-all error for unreachable hosts. "You can't get there from here." TCP/IP scenario: The local network system could generate this

WSAEADDRINUSE 10048 Address already in use. Winsock Error 10054 Fix Unlike Berkeley, however, WinSock v1.1 doesn't ascribe this error to any functions. WinSock description: No equivalent WinSock functions: WSAEMFILE (10024) Too many open files. This message has a slightly different meaning from WSAEAFNOSUPPORT.

Socket Error Codes Linux

All sockets are created with an associated address family (that is, AF_INET for Internet Protocols) and a generic protocol type (that is, SOCK_STREAM). page 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. Socket Error 10054 This normally results from an attempt to bind to an address that is not valid for the local computer. Socket Error 10053 See also: WSAECONNABORTED, WSAECONNRESET, WSAENETRESET WSAETOOMANYREFS (10059) Too many references; can't splice Berkeley description: too many references to some kernel-level object; the associated resource has run out.

Returned when a system call that should never fail does fail. Check This Out This is a generic error code, returned under various conditions. WinSock functions: With a datastream socket: connect() and FD_CONNECT WSAAsyncelect() notification message. I chose 54321 as the port following an msdn example. Socket Error 10054 Connection Reset By Peer

If it does respond, then this problem might have been a transient one (so you can reconnect now), or the server application you were connected to might have terminated (so you They signal unusual error conditions for which there's no WinSock error equivalent. WSA_QOS_ADMISSION_FAILURE 11010 QoS admission error. Source The ICMP message means that a router can't forward the IP datagram, possibly because it didn't get a response to the ARP request (which might mean the destination host is down).

WSAEPROTONOSUPPORT (10043) Protocol not supported. Socket Error 10061 Connection Refused User suggestions: see WSAHOST_NOT_FOUND for details. In fact, on occasion you can benefit if the WinSock implementation returns these other errors.

Ping a local host to verify that your local network is still functioning (if on a serial connection, see next step) Ping your local router address.

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 The WinSock implementation will not allow you to send after this. WinSock functions: connect(), FD_CONNECT Additional functions: Any function that does I/O on the network could generate this error, and the WSAAsyncSelect() events FD_OOB, FD_READ, FD_WRITE. Socket Error 11001 What does "M.C." in "M.C.

Too many references to some kernel object. WinSock functions: Any function capable of a blocking operation can return this error: accept(), close socket(), connect(),gethostbyname(), gethostbyaddr(), getprotobyname(), getprotobynumber(), getservbyname(), getservbyport(), recv(), recvfrom(), select(), send(), sendto() Additional functions: Any of By calling shutdown a partial close of a socket is requested, which is a signal that sending or receiving, or both have been discontinued. have a peek here You should simply ignore this error when it occurs.

No such host is known. If so, then the application might have had a problem resolving the name (see suggestions at WSATRY_AGAIN for more information). WSAEOPNOTSUPP 10045 Operation not supported. User suggestions: see WSAENETUNREACH for details WinSock functions: Additional functions: Any function that does network I/O.

User suggestions: Do you have the WinSock DLL that supports the version of the WinSock specification required by the application? Ran out of user quota. What does Winsock Error 10049 mean?

Winsock error 10049 typically occurs when you attempt to create a socket with an address not on this machine. Browse other questions tagged c# c++ or ask your own question.

msdn winsock error codes What am I doing wrong in the Connect call? WinSock functions: Additional functions: For Berkeley compatibility, the socket() function should fail with this error if an unsupported address family is requested. 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. This is not a soft error, another type of name server request may be successful.

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. WinSock description: Same as Berkeley, and then some. Any function that takes a socket as an input parameter--except close socket()--could potentially fail with this error. This is usually caused by one or more of the function pointers being NULL.

The item is not available locally. In the c++ dll I have the following code SOCKADDR_IN server; server.sin_port=htons (54321); server.sin_family = AF_INET; server.sin_addr.s_addr = INADDR_ANY; // Connect to server. 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. Applications that use WSAGetOverlappedResult (with the fWait flag set to FALSE) in a polling mode to determine when an overlapped operation has completed, get this error code until the operation is

WSAEPROVIDERFAILEDINIT 10106 Service provider failed to initialize. If you have more than one server configured, the hostname query fails only after the WinSock DLL has queried all servers.
