WSAEISCONN 10056 Socket is already connected. WSAECONNABORTED 10053 Software caused connection abort. Always be sure to allocate enough space. Developer suggestions: to make your application more portable: with datagram sockets don't use connect() and sendto() on the same datagram socket in an application, and always "disconnect" before calling connect() more

Typically, only one usage of each socket address (protocol/IP address/port) is permitted. WSAEPFNOSUPPORT 10046 Protocol family not supported. Ping a host on the same subnet as the host you were connected to (if you know one). An attempt was made to access a socket in a way forbidden by its access permissions. 10014WSAEFAULTBad address.

Socket Error 10054

You’ll be auto redirected in 1 second. WinSock description: No equivalent in WinSock. Note the British spelling (with an 'S' instead of a 'Z'). For information on how to handle error codes when porting socket applications to Winsock, see Error Codes - errno, h_errno and WSAGetLastError.

You are unlikely to encounter them. NOTE: The MAKEWORD macro referenced in the code fragment is not available in the WINSOCK.H header file or in any standard header files. The X86 and X64 chips normally tolerate misaligned structures with a small performance penalty, but operating system calls such as TransmitPackets often do not. Socket Error 11004 An operation was attempted on something that is not a socket.

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 or any other socket) Socket Error Codes Linux You need to call htons() to translate a constant value to network byte order before assigning it to the sin_port field in the sockaddr structure. WinSock description: Same as Berkeley. Note: Although connect() and FD_CONNECT also have this error listed, the documentation specifically states that WSAEADDRNOTAVAIL is appropriate if INADDR_ANY is passed as a destination address.

A socket operation encountered a dead network. Winsock Error 10061 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 This error occurs if an application passes an invalid pointer value, or if the length of the buffer is too small. WSAEBADF 10009 Bad file number.

Socket Error Codes Linux

The protocol family has not been configured into the system or no implementation for it exists. A request to send or receive data was disallowed because the socket is not connected and (when sending on a datagram socket using sendto) no address was supplied. Socket Error 10054 In fact, on occasion you can benefit if the WinSock implementation returns these other errors. Socket Error 10053 WinSock functions: socket() See also: WSAESOCKTNOSUPPORT WSAEPROTOTYPE (10041) Protocol wrong type for socket.

WinSock description: Same as Berkeley. An existing connection was forcibly closed by the remote host. An object with an invalid ObjectLength field was specified in the QoS provider-specific buffer. For instance, if the length of a struct sockaddr is not equivalent to the sizeof(struct sockaddr). Socket Error 10054 Connection Reset By Peer

WinSock description: No equivalent. WSATRY_AGAIN 11002 Nonauthoritative host not found. Berkeley description: A connect or send request failed because the connected party did not properly respond after a period of time. (The timeout period is dependent on the communication protocol.) WinSock Source It indicates a problem in the Windows sockets software.

WSAECANCELLED 10103 Call has been canceled. Socket Error 10061 Connection Refused WSA_QOS_ADMISSION_FAILURE 11010 QoS admission error. SOCKETS ERROR: recv call detected a closed { server | console } connection This message appears when the Client is reading TCP data, and indicates that the Client received an abnormal

Typically, though, WinSock generates WSAENETUNREACH when it receives a "host unreachable" ICMP message from a router instead of WSAEHOSTUNREACH.

WSAVERNOTSUPPORTED 10092 Winsock version not supported. If you used a hostname, did it resolve to the correct address? 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. Winsock Error 10054 Fix 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. WSAStartup may fail with this error if the limit has been reached. 10091WSASYSNOTREADYNetwork subsystem is unavailable. By calling shutdown() you do a partial close of a socket, which means you have discontinued sending. have a peek here Berkeley description: Too many open files.

a TCP reset received from remote host). WSAHOST_NOT_FOUND 11001 Host not found. The application may be accessing a socket that the current active task does not own (that is, trying to share a socket between tasks), or WSACleanup has been called too many Cahn For further information on these books and for a list of forthcoming titles, please visit our website at...‎Appears in 37 books from 2001-2008About the author(2004)David Makofske has over ten years

WSA_QOS_SENDERS 11006 QoS senders. recv(), recvfrom(), send(), sendto(): MSG_OOB was specified, but the socket is not of type SOCK_STREAM Developer suggestions: don't do that. For example, a socket call requests a SOCK_DGRAM socket, but specifies a stream protocol. WSA_QOS_TRAFFIC_CTRL_ERROR 11014 QoS traffic control error.

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. WSAEPROTOTYPE 10041 Protocol wrong type for socket. User suggestions: see WSAHOST_NOT_FOUND for details. No connection could be made because the target computer actively refused it.

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   WSAGetLastError() and WSAIsBlocking() cannot fail. This message can occur at the beginning of a define, process, clone, or switchaudit command. SO_DEBUG, SO_DONTROUTE, SO_RCVBUF, SO_SNDBUF, TCP_NODELAY: optional socket options.

The following table provides an index to the most likely creator of an error in any given range: Error NumberGenerated by Error < ZeroOperating System Error or WinSock network layer ZeroNo The content you requested has been removed. This error occurs when the sin_port value is zero in a sockaddr_in structure for connect() or sendto(). An unknown, invalid or unsupported option or level was specified in a getsockopt or setsockopt call.

This error is returned by WSAStartup if the Windows Sockets implementation cannot function at because the underlying system it uses to provide network services is currently unavailable. You can avoid making the mistake of trying to send on a socket after you've initiated a close, by keeping track of the socket state in your application (and checking it It indicates that the Windows sockets software is incompatible with that used by the Client. 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
