Windows Socket Version 2 Api Error Code Msdn


For example, new name service functions (getaddrinfo and getnameinfo, for example) were added that support both IPv6 and IPv4 on Windows XP and later. Winsock performs an alertable wait in this situation, which can be interrupted by an asynchronous procedure call (APC) scheduled on the same thread. These defines remain commented out in the Winsock2.h header within an #ifdef 0 and #endif block. There are some very serious drawbacks. http://pubdimensions.com/socket-error/windows-socket-version-2-api-error-code-documentation-in-msdn.php

This error is returned if the specified address pointed to by the name parameter is not a valid local IP address on this computer. So a multicast application would first select an IPv4 or IPv6 address on the local computer, the wildcard IPv4 address (INADDR_ANY), or the wildcard IPv6 address (in6addr_any). Otherwise, the value SOCKET_ERROR (-1) is returned and a specific error number can be retrieved by calling the WSAGetLastError function. For Winsock functions that return a handle, a return value of INVALID_SOCKET (0xffff) indicates an error and a specific error number can be retrieved by calling WSAGetLastError. click for more info

Socket Error 10038

Binding to a specific port number other than port 0 is discouraged for client applications, since there is a danger of conflicting with another socket already using that port number on See ASP.NET Ajax CDN Terms of Use – http://www.asp.net/ajaxlibrary/CDN.ashx. ]]> Developer resources Microsoft developer Windows The maximum value for the client dynamic port range can be changed by setting a value under the following registry key: HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters The MaxUserPort registry value sets the value to use

WSAEADDRINUSE Only one usage of each socket address (protocol/network address/port) is normally permitted. Return value If no error occurs, bind returns zero. Socket Error 10049 So for example, ECONNREFUSED was defined as WSAECONNREFUSED in the Winsock.h header file.

These can be used to provide some compatibility with UNIX, BSD, and Linux socket programming. Socket Error Codes Linux WSAEFAULT The system detected an invalid pointer address in attempting to use a pointer argument in a call. This is a change from Windows Server 2003 and earlier where the dynamic client port range was a value between 1025 and 5000. https://msdn.microsoft.com/en-us/library/windows/desktop/cc507522(v=vs.85).aspx We appreciate your feedback.

Socket Error Codes Linux

The error codes returned by Windows Sockets are similar to UNIX socket error code constants, but the constants are all prefixed with WSA. https://msdn.microsoft.com/en-us/library/windows/desktop/ms741580(v=vs.85).aspx Note  When issuing a blocking Winsock call such as bind, Winsock may need to wait for a network event before the call can complete. Socket Error 10038 WSAENOTSOCK An operation was attempted on something that is not a socket. Socket Error 10054 Connection Reset By Peer 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.

This error is returned if the descriptor in the s parameter is not a socket.   Remarks The bind function is required on an unconnected socket before subsequent calls to the Get More Info If the IrDA socket was previously bound to a service name using bind, the connect function will fail with SOCKET_ERROR. Handling Winsock Errors Most Windows Sockets 2 functions do not return the specific cause of an error when the function returns. A name consists of three parts when using the Internet address family: The address family. Socket Error 10053

WSAENOBUFS An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full. A Winsock error code can be converted to an HRESULT for use in a remote procedure call (RPC) using HRESULT_FROM_WIN32. 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 useful reference We appreciate your feedback.

So in Winsock applications the WSAEWOULDBLOCK error code would be returned, while in UNIX applications the EWOULDBLOCK error code would be returned. Winsock Error 10061 Use the bind function to establish the local association of the socket by assigning a local name to an unnamed socket. The Winsock2.h header file included with the Microsoft Windows Software Development Kit (SDK), Platform Software Development Kit (SDK), and Visual Studio still contains a commented out block of defines within an

Also, the BSD socket errors are defined to very different values than are used in UNIX, BSD, and Linux programs.

If the service name is of the form "LSAP-SELxxx," where xxx is a decimal integer in the range 1-127, the address indicates a specific LSAP-SEL xxx rather than a service name. This is because error codes returned by certain Windows Sockets functions fall into the standard range of error codes as defined by Microsoft C©. See ASP.NET Ajax CDN Terms of Use – http://www.asp.net/ajaxlibrary/CDN.ashx. ]]> Winsock Error Windows 7 Furthermore, it is not possible for an application to assign a new value to errno. (In Windows Sockets, the function WSASetLastError may be used for this purpose.) Typical BSD Style C++

If a wildcard address was specified, then Windows will select the local IP address to use. This error is returned if a process on the computer is already bound to the same fully qualified address and the socket has not been marked to allow address reuse with Although this order of operations is not mandatory, it is strongly recommended. this page A host address.

Some Winsock functions return a value of zero if successful. For more information, see SO_EXCLUSIVEADDRUSE and Using SO_REUSEADDR and SO_EXCLUSIVEADDRUSE.   For multicast operations, the preferred method is to call the bind function to associate a socket with a local IP If an application developer insists on using the BSD error codes for compatibility, then an application may choose to include a line of the form: C++ Copy #include #define errno Windows 8.1 and Windows Server 2012 R2: This function is supported for Windows Store apps on Windows 8.1, Windows Server 2012 R2, and later.
