Windows Sockets Version 2 Api Error Code Msdn


WSAEPROTONOSUPPORT The specified protocol is not supported. This error may also be returned for protocol and service queries, and means that the specified name could not be found in the relevant database. This address family is not supported on Windows Vista and later. All functions that allow overlapped operation (WSASend, WSARecv, WSASendTo, WSARecvFrom, and WSAIoctl) also support nonoverlapped usage on an overlapped socket if the values for parameters related to overlapped operation are NULL. have a peek here

The current Windows Sockets implementation does not support the Windows Sockets specification version requested by the application. Return value The return value indicates the error code for this thread's last Windows Sockets operation that failed. An invalid or unrecognized service type was found in the QoS flowspec. The Windows Sockets provider for NetBIOS is supported on 32-bit versions of Windows.

Socket Error 10054

This address family is not supported on Windows Vista and later. This address family is only supported if the Windows Sockets provider for NetBIOS is installed. Downloads and tools Windows 10 dev tools Visual Studio Windows SDK Windows Store badges Essentials API reference (Windows apps) API reference (desktop apps) Code samples How-to guides (Windows apps) Learning resources Sockets without the overlapped attribute can be created by using WSASocket.

  • WSAEINPROGRESS 10036 Operation now in progress.
  • 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).
  • These error codes and a short text description associated with an error code are defined in the Winerror.h header file.
  • WSAENETDOWN 10050 Network is down.
  • Syntax C++ Copy SOCKET WSAAPI socket( _In_ int af, _In_ int type, _In_ int protocol ); Parameters af [in] The address family specification.
  • No more results can be returned by the WSALookupServiceNext function.
  • WSAETIMEDOUT An attempt to connect timed out without establishing a connection.
  • So in Winsock applications the WSAEWOULDBLOCK error code would be returned, while in UNIX applications the EWOULDBLOCK error code would be returned.
  • An invalid QoS filter style was used.

WSAENOBUFS 10055 No buffer space available. Note that the Ws2def.h header file is automatically included in Winsock2.h, and should never be used directly.

Socket Error 10049 Error Codes - errno, h_errno and WSAGetLastError In Winsock applications, error codes are retrieved using the WSAGetLastError function, the Windows Sockets substitute for the Windows GetLastError function.

An example of this type is the Pragmatic General Multicast (PGM) multicast protocol implementation in Windows, often referred to as reliable multicast programming. Socket Error Codes Linux The FormatMessage function can be used to obtain the message string for the returned error. protocol [in] The protocol to be used. Either the socket handle parameter did not reference a valid socket, or for select, a member of an fd_set was not valid.

sockaddr_in clientService; clientService.sin_family = AF_INET; clientService.sin_addr.s_addr = inet_addr(""); clientService.sin_port = htons(27015); //---------------------- // Connect to server. Socket Error 11004 A completion indication will be given later when the operation has been completed. WSANOTINITIALISED 10093 Successful WSAStartup not yet performed.

For server applications that need to bind multiple sockets to the same port number, consider using setsockopt (SO_REUSEADDR). WSAEPROVIDERFAILEDINIT 10106 Service provider failed to initialize. Socket Error 10054 This could indicate a serious failure of the network system (that is, the protocol stack that the Windows Sockets DLL runs over), the network interface, or the local network itself. Socket Error 10053 Issuing another blocking Winsock call inside an APC that interrupted an ongoing blocking Winsock call on the same thread will lead to undefined behavior, and must never be attempted by Winsock

WSA_QOS_EPSFILTERSPEC 11028 Invalid QoS provider-specific filterspec. This error is returned by the WSCGetProviderInfo and WSCGetProviderInfo32 functions if the protocol entry specified could not be found. This error is returned if the af parameter is set to AF_UNSPEC and the type and protocol parameter are unspecified. An invalid or inconsistent flowspec was found in the QOS structure. Socket Error 10054 Connection Reset By Peer

The support for the specified socket type does not exist in this address family. WSA_QOS_GENERIC_ERROR 11015 QoS generic error. netsh winsock show catalog Support for sockets with type SOCK_RAW is not required, but service providers are encouraged to support raw sockets as practicable. Check This Out This error is returned if either a service provider's DLL could not be loaded (LoadLibrary failed) or the provider's WSPStartup or NSPStartup function failed.

The WSAGetLastError function should not be used to check for an extended error value on receipt of an asynchronous message. Socket Error 10061 Connection Refused WSAEMFILE 10024 Too many open files. IPPROTO_UDP 17 The User Datagram Protocol (UDP).

This usually means the local software knows no route to reach the remote host.

The default destination can be changed by simply calling connect again, even if the socket is already connected. WSA_QOS_EFILTERCOUNT 11021 Incorrect QoS filter count. If such a socket is connected to a specific peer, datagrams can be sent to that peer using send and can be received only from this peer using recv. Windows Socket Error Windows 10 A message sent on a datagram socket was larger than the internal message buffer or some other network limit, or the buffer used to receive a datagram was smaller than the

Client applications usually need not call bind at all—connect chooses an unused port automatically. Note that once a socket is bound, it cannot be used for establishing an outbound connection. To specifically reset the extended error code, use the WSASetLastError function call with the iError parameter set to zero. this contact form WSAENETUNREACH The network cannot be reached from this host at this time.

Example Code The following example demonstrates the use of the socket function to create a socket that is bound to a specific transport service provider.. For compatibility with Berkeley UNIX (BSD), early versions of Windows (Windows 95 with the Windows Socket 2 Update and Windows 98, for example) redefined regular Berkeley error constants typically found in errno.h on BSD A blocking operation was interrupted by a call to WSACancelBlockingCall. If they do, they must be prepared to handle WSAEINVAL and WSAEWOULDBLOCK error values the same way that they handle WSAEALREADY, to assure robust operation.

AfMeaning AF_UNSPEC 0 The address family is unspecified. The service cannot be found in the specified name space. The Windows function is indicating a problem with one or more parameters. This address family is only supported if the NWLink IPX/SPX NetBIOS Compatible Transport protocol is installed.

When the success or failure outcome becomes known, it may be reported in one of two ways, depending on how the client registers for notification. There are some very serious drawbacks. WSAEOPNOTSUPP 10045 Operation not supported. Returned by WSARecv and WSARecvFrom to indicate that the remote party has initiated a graceful shutdown sequence.

WSAEMFILE No more socket descriptors are available. C++ Copy #ifndef UNICODE #define UNICODE 1 #endif // link with Ws2_32.lib #pragma comment(lib,"Ws2_32.lib") #include #include #include #include // Needed for _wtoi int __cdecl wmain(int argc, wchar_t This documentation is archived and is not being maintained. Too many open sockets.

Windows Phone 8: This function is supported for Windows Phone Store apps on Windows Phone 8 and later. SOCK_SEQPACKET 5 A socket type that provides a pseudo-stream packet based on datagrams.   In Windows Sockets 2, new socket types were introduced. WSAECONNREFUSED 10061 Connection refused. However, the operation proceeds.

The requested service provider is invalid. Some error codes defined in the Winsock2.h header file are not returned from any function. No more results can be returned by the WSALookupServiceNext function. If the address member of the structure specified by name is filled with zeros, the socket will be disconnected.
