The first 2 bytes in this block (corresponding to the sa_family member of the sockaddr structure) must contain the address family that was used to create the socket. Service providers are free to regard it as a pointer to a block of memory of size namelen. It is cast this way for Winsock 1.1 compatibility. In Winsock 2.2, th e name parameter is not strictly interpreted as a pointer to a sockaddr structure.

Use the bind function to establish the local association of the socket by assigning a local name to an unnamed socket.Ī name consists of the three parts when using the Internet address family. When a socket is created with a call to the socket (Windows Sockets) function, it exists in a name space (address family) but has no name assigned to it. The bind function is used to bind to either connection-oriented (stream) or connectionless (datagram) sockets. This function is used on an unconnected socket before subsequent calls to the connect (Windows Sockets) or listen function.

If an error occurs, it returns SOCKET_ERROR, and a specific error code can be retrieved by calling WSAGetLastError. If no error occurs, this function returns zero. Length of the value in the name parameter. Address to assign to the socket from the sockaddr structure. Descriptor identifying an unbound socket. int bind(SOCKET s,const struct sockaddr FAR* name,int namelen)
