Microsoft C description: Bad file number. Thirteen errors have "" next to the list of WinSock functions that can produce them. WSA_QOS_ESERVICETYPE 11016 QoS service type 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.

WSA_QOS_RECEIVERS 11005 QoS receivers. Additional functions: a generic description of the type of functions that can return this error, which may include functions other than those listed by the WinSock specification. WSA_IO_INCOMPLETE 996 Overlapped I/O event object not in signaled state. If we modify our Winsock initialization code slightly...

Socket Error 10054

User suggestions: Check that the WINSOCK.DLL file is in the current path Check that the WINSOCK.DLL file is from the same vendor as your underlying protocol stack. When we are finished, we should be able to troubleshoot our applications so we can pinpoint where a problem may exist with greater efficiency. The socket is marked as non-blocking (non-blocking operation mode), and the requested operation is not complete at this time. WSAEINVALIDPROVIDER 10105 Service provider is invalid.

  1. The FormatMessage function can be used to obtain the message string for the returned error.
  2. Change the following line to; SOCKET Socket=socket(AF_INET,SOCK_STREAM,IPPROTO_UDP); What we have done here is mix and match TCP/IP elements (SOCK_STREAM) and UDP elements (IPPROTO_UDP), which is a big no no.
  3. WinSock description: Same as Berkeley.
  4. Berkeley description: A pathname lookup involved more than 8 symbolic links.
  5. WSAEWOULDBLOCK 10035 Resource temporarily unavailable.
  6. For example, a socket call requests a SOCK_DGRAM socket, but specifies a stream protocol.
  7. A reserved policy element was found in the QoS provider-specific buffer.   Requirements Header Winsock2.h; Winerror.h See also Error Codes - errno, h_errno and WSAGetLastError Handling Winsock Errors FormatMessage WSAGetLastError  
  8. In some cases these errors are platform dependent.

WinSock functions: accept(), bind(), getsockname(), ioctlsocket(), listen(), recv(), recvfrom(), select(), send(), setsockopt(), shutdown(), WSAStartup(), WSAAsyncSelect(), WSACancelAsyncRequest(), WSACancelBlockingCall, FD_CONNECT Additional functions: Any WinSock function that takes input parameters that could be invalid Any application that uses a blocking socket or calls any blocking functions must handle this error. it may occur when a pointer to a structures is invalid or when a value in structure field is invalid). Socket Error 10049 Developer suggestions: Assume bind() will fail with this error.

An invalid QoS filter type was used. What Is A Socket Error An invalid shaping rate object was found in the QoS provider-specific buffer. These conditions are more likely to be indicated by the error WSAETIMEDOUT. WSA_QOS_EPSFLOWSPEC 11027 Invalid QoS provider-specific flowspec.

The connection has been broken due to keep-alive activity detecting a failure while the operation was in progress. Wsagetlasterror 0 If you have more than one server configured, the hostname query fails only after the WinSock DLL has queried all servers. WSA_NOT_ENOUGH_MEMORY 8 Insufficient memory available. WSAESHUTDOWN 10058 Cannot send after socket shutdown.

What Is A Socket Error

An object with an invalid ObjectLength field was specified in the QoS provider-specific buffer. WinSock functions: connect(), sendto(), FD_CONNECT Additional functions: Any function that does network I/O: recv(), recvfrom(), send(), FD_READ, FD_WRITE See also: WSAEHOSTUNREACH WSAENOBUFS (10055) No buffer space available. Socket Error 10054 Run two instances of the server (with our updated code) and see what happens. Socket Error 10053 In some instances, it also refers to the current state of the socket—for instance, calling accept on a socket that is not listening.

WSA_QOS_NO_RECEIVERS 11008 QoS no receivers. A call to the WSALookupServiceEnd function was made while this call was still processing. He also lurks around the forums as Hieran_Del8. It also has a specific meaning for setsockopt(). Socket Error 10054 Connection Reset By Peer

Users should check: That the appropriate Windows Sockets DLL file is in the current path. This particular code can be used by the supplier to identify the error made. WinSock description: No equivalent. WinSock description: The current WinSock implementation does not support the Windows Sockets specification version requested by the application.

For instance, this error will occur if you try to run two applications that have FTP servers. Wsaeconnreset 10054 This documentation is archived and is not being maintained. A database query failed because it was actively refused.

This could be due to an out of memory error or to an internal QoS provider error.

In some instances, it also refers to the current state of the socket input parameter. Show Amine Khaldi added a comment - 2016-11-16 15:46 What was the commit revision for this one? SO_ACCEPTCONN, SO_DONTLINGER, SO_KEEPALIVE, SO_LINGER, SO_OOBINLINE and TCP_NODELAY are not supported on sockets of type SOCK_DGRAM. Socket Error 11004 Cc hater Hide Permalink hater added a comment - 2016-10-07 19:34 A testcase is needed that the change is fine.

WSAEPFNOSUPPORT 10046 Protocol family not supported. The error can also occur in an attempt to rename a file or directory or to remove an existing directory. Eventually the system becomes overloaded with problems and begins to crash displaying system errors. WinSock description: Either your application hasn't called WSAStartup(), or WSAStartup() failed, or--possibly--you are accessing a socket which the current active task does not own (i.e.

We suggest local configuration changes that might remedy the problem, and network and server conditions that might be the cause. For information on how to handle error codes when porting socket applications to Winsock, see Error Codes - errno, h_errno and WSAGetLastError. 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. Otherwise change looks legit.

For instance, you might get WSAEBADF in place of WSAENOTSOCK on a system that provides some socket and file handle equivalency. WSAESTALE 10070 Stale file handle reference. A required address was omitted from an operation on a socket. There are only a few possible causes for this error: you tried to connect to the wrong port.

It is designed to diagnose problems on your computer and fix them in just a few minutes with only a few mouse clicks. Download WSAVERNOTSUPPORTED Repair Tool File Size: 8 MB For example, the optional type SOCK_RAW might be selected in a socket call, and the implementation does not support SOCK_RAW sockets at all. For more information on debugging problems, see Chapter 13, "Debugging." Errorless Functions Eight of the forty-six functions in the Windows Sockets API are not referenced in any of the "WinSock function" 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.

Berkeley description: An operation that takes a long time to complete (such as a connect()) was attempted on a non-blocking socket. (see ioctl()). User suggestions: see WSAHOST_NOT_FOUND for details. WSA_IO_PENDING 997 Overlapped operations will complete later. Once we are happy that Winsock has initialized correctly, we can now use a handy function to address any further failures.

connect(), send(), recv(), et cetera). WSAETIMEDOUT 10060 Connection timed out. WinSock description: Same as Berkeley, and then some. However, the WSAEPROTONOSUPPORT is another possible equivalent for WinSock to use in place of this error.

If you're on a serial connection, your local router is the IP address of the host you initially logged onto with SLIP or PPP. As you can see from the comprehensive list of WinSock functions, this error is the catch-all. 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
