Windows Socket Version 2 Api Error Code Msdn


A Winsock error code can be converted to an HRESULT for use in a remote procedure call (RPC) using HRESULT_FROM_WIN32. 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 Application developers are very strongly encouraged to use the WSA error constants in socket applications. This socket can then be used to receive multicast packets from the multicast group using the recv, recvfrom, WSARecv, WSARecvEx, WSARecvFrom, or WSARecvMsg functions. news

WSAENOBUFS An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full. The WSAGetLastError function is intended to provide a reliable way for a thread in a multithreaded process to obtain per-thread error information. Local names are not exposed in IrDA. WSAEADDRINUSE Only one usage of each socket address (protocol/network address/port) is normally permitted. https://msdn.microsoft.com/en-us/library/windows/desktop/ms740668(v=vs.85).aspx

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. 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 Examples The following example demonstrates the use of the bind function. Error codes set by Windows Sockets are not made available through the errno variable.

  • After the bind function completes, an application would then join the multicast group of interest.
  • Use the bind function to establish the local association of the socket by assigning a local name to an unnamed socket.
  • 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
  • Handling Winsock Errors Most Windows Sockets 2 functions do not return the specific cause of an error when the function returns.
  • There are some very serious drawbacks.
  • WSAEADDRNOTAVAIL The requested address is not valid in its context.
  • It is cast this way for Windows Sockets 1.1 compatibility.
  • 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.
  • 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++

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). This error is returned of not enough buffers are available or there are too many connections. Windows Sockets 2 added functions and features with other Windows Sockets error codes returned in addition to those listed in the original Winsock specification. Socket Error 10049 For more information on how to join a multicast group, see the section on Multicast Programming.

For example, new name service functions (getaddrinfo and getnameinfo, for example) were added that support both IPv6 and IPv4 on Windows XP and later. 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 In the Microsoft Windows Software Development Kit (SDK), HRESULT_FROM_WIN32 is defined as an inline function in the Winerror.h header file. https://msdn.microsoft.com/en-us/library/windows/desktop/cc507522(v=vs.85).aspx Otherwise, the value SOCKET_ERROR (-1) is returned and a specific error number can be retrieved by calling the WSAGetLastError function.

However, application developers are strongly discouraged from uncommenting this block because of inevitable conflicts with errno.h in most applications. Socket Error 11004 In earlier versions of the Platform Software Development Kit (SDK), HRESULT_FROM_WIN32 was defined as a macro in the Winerror.h header file. 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. In Windows Sockets 2, the name parameter is not strictly interpreted as a pointer to a sockaddr structure.

We appreciate your feedback. navigate to this website This documentation is archived and is not being maintained. 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. 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 Socket Error 10053

You must restart the computer for this setting to take effect. Note  When issuing a blocking Winsock call such as bind, Winsock may need to wait for a network event before the call can complete. Return value If no error occurs, bind returns zero.

This error is returned if nn attempt to bind a datagram socket to the broadcast address failed because the setsockopt option SO_BROADCAST is not enabled. Winsock Error 10061 Otherwise, it returns SOCKET_ERROR, and a specific error code can be retrieved by calling WSAGetLastError. WSAEFAULT The system detected an invalid pointer address in attempting to use a pointer argument in a call.

Otherwise an implicit bind to the wildcard address using the sendto,WSASendMsg , or WSASendTo functions might result in a different local IP address being used for send operations.

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 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 Yes No Additional feedback? 1500 characters remaining Submit Skip this Thank you! Winsock Error Windows 7 WSAEACCES An attempt was made to access a socket in a way forbidden by its access permissions.

Also, the BSD socket errors are defined to very different values than are used in UNIX, BSD, and Linux programs. The dynamic client port range can be set differently for UDP and TCP and also for IPv4 and IPv6. 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 click site If a wildcard address was specified, then Windows will select the local IP address to use.

IrDA client sockets therefore, must never call the bind function before the connect function. The application can use getsockname after calling bind to learn the address and the port that has been assigned to the socket. 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, A complete list of possible error codes returned by Windows Sockets functions is given in the section on Windows Sockets Error Codes.

So in Winsock applications the WSAEWOULDBLOCK error code would be returned, while in UNIX applications the EWOULDBLOCK error code would be returned. 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. This is a change from Windows Server 2003 and earlier where the dynamic client port range was a value between 1025 and 5000.

name [in] A pointer to a sockaddr structure of the local address to assign to the bound socket . This is because error codes returned by certain Windows Sockets functions fall into the standard range of error codes as defined by Microsoft C©. On Windows Vista and later, the dynamic client port range is a value between 49152 and 65535.
