Windows Socket Version 2 Api Error Code Msdn

WSAEINVAL An invalid argument was supplied. Some Winsock functions return a value of zero if successful. 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 This is a change from Windows Server 2003 and earlier where the dynamic client port range was a value between 1025 and 5000. this contact form

Otherwise, the value SOCKET_ERROR (-1) is returned and a specific error number can be retrieved by calling the WSAGetLastError function. Return value If no error occurs, bind returns zero. namelen [in] The length, in bytes, of the value pointed to by the name parameter.

Socket Error 10038

Syntax C++ Copy int bind( _In_ SOCKET                s, _In_ const struct sockaddr *name, _In_ int                   namelen ); Parameters s [in] A descriptor identifying an unbound socket. If an application does not care what local address is assigned, specify the constant value INADDR_ANY for an IPv4 local address or the constant value in6addr_any for an IPv6 local address Otherwise, it returns SOCKET_ERROR, and a specific error code can be retrieved by calling WSAGetLastError.

Service names such as these allow server applications to accept incoming connections directed to a specific LSAP-SEL, without first performing an ISA service name query to get the associated LSAP-SEL.

Socket Error 10049 On Windows Vista and later, the dynamic client port range can be viewed and changed using netsh commands.

The error codes returned by Windows Sockets are similar to UNIX socket error code constants, but the constants are all prefixed with WSA. Socket Error Codes Linux bind function The bind function associates a local address with a socket. On Windows Vista and later, the dynamic client port range is a value between 49152 and 65535. this page 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.

A complete list of possible error codes returned by Windows Sockets functions is given in the section on Windows Sockets Error Codes. Socket Error 11004 Windows Phone 8: This function is supported for Windows Phone Store apps on Windows Phone 8 and later. 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++ Otherwise, an error WSAEFAULT occurs.

  • One example of this service name type is a non-Windows device that does not support IAS.
  • In the Microsoft Windows Software Development Kit (SDK), HRESULT_FROM_WIN32 is defined as an inline function in the Winerror.h header file.
  • Additionally, for the getXbyY class of functions, error codes are not made available through the h_errno variable.
  • Application developers are very strongly encouraged to use the WSA error constants in socket applications.
  • IrDA client sockets therefore, must never call the bind function before the connect function.
  • In Windows Sockets 2, the name parameter is not strictly interpreted as a pointer to a sockaddr structure.
  • There are some very serious drawbacks.
  • A Winsock error code can be converted to an HRESULT for use in a remote procedure call (RPC) using HRESULT_FROM_WIN32.
  • The bind function is required before the use of the send or WSASend functions which do not perform an implicit bind and are allowed only on connected sockets, which means the

The the multicast application would then call the bind function with this address in the in the sa_data member of the name parameter to associate the local IP address with the https://msdn.microsoft.com/en-us/library/windows/desktop/ms741580(v=vs.85).aspx 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 Socket Error 10038 For TCP/IP, if the port is specified as zero, the service provider assigns a unique port to the application from the dynamic client port range. Socket Error 10054 Connection Reset By Peer For more information, see the SO_REUSEADDR socket option in the SOL_SOCKET Socket Options reference, Using SO_REUSEADDR and SO_EXCLUSIVEADDRUSE, and SO_EXCLUSIVEADDRUSE.

You must restart the computer for this setting to take effect. Yes No Additional feedback? 1500 characters remaining Submit Skip this Thank you! Socket Error 10053

So for example, ECONNREFUSED was defined as WSAECONNREFUSED in the Winsock.h header file. We appreciate your feedback. service.sin_family = AF_INET; service.sin_addr.s_addr = inet_addr("127.0.0.1"); service.sin_port = htons(27015); //---------------------- // Bind the socket. navigate here 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

This documentation is archived and is not being maintained. Winsock Error 10061 The bind function may also be used on an unconnected socket before subsequent calls to the connect, ConnectEx, WSAConnect, WSAConnectByList, or WSAConnectByName functions before send operations. Winsock performs an alertable wait in this situation, which can be interrupted by an asynchronous procedure call (APC) scheduled on the same thread.

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.

If a source file includes code which inspects errno for both socket and non-socket functions, this mechanism cannot be used. This error is returned if the name parameter is NULL, the name or namelen parameter is not a valid part of the user address space, the namelen parameter is too small, Local names are not exposed in IrDA. Winsock Error Windows 7 Examples The following example demonstrates the use of the bind function.

Error codeMeaning WSANOTINITIALISED Note  A successful WSAStartup call must occur before using this function.   WSAENETDOWN The network subsystem has failed. See ASP.NET Ajax CDN Terms of Use – http://www.asp.net/ajaxlibrary/CDN.ashx. ]]> Windows Sockets 2 added functions and features with other Windows Sockets error codes returned in addition to those listed in the original Winsock specification. his comment is here 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

For more information, see KB 929851. The WSAGetLastError function is intended to provide a reliable way for a thread in a multithreaded process to obtain per-thread error information. This is because error codes returned by certain Windows Sockets functions fall into the standard range of error codes as defined by Microsoft C©. We appreciate your feedback.

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 Although this order of operations is not mandatory, it is strongly recommended. Additional functions have been added over time to enhance Winsock for use by developers. These defines remain commented out in the Winsock2.h header within an #ifdef 0 and #endif block.

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). In subsequent versions of Windows (Windows NT 3.1 and later) these defines were commented out to avoid conflicts with errno.h used with Microsoft C/C++ and Visual Studio. The bind function may also be used to bind to a raw socket (the socket was created by calling the socket function with the type parameter set to SOCK_RAW). Handling Winsock Errors Most Windows Sockets 2 functions do not return the specific cause of an error when the function returns.

WSAENOBUFS An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full. The bind function might be used before send operations using the sendto,WSASendMsg, or WSASendTo functions if an application wanted to select a specific local IP address on a local computer with These can be used to provide some compatibility with UNIX, BSD, and Linux socket programming. Some of the older IPv4-only name service functions (the getXbyY class of functions, for example) have been deprecated.
