Synopsis

Writes data to the socket. On UNIX, VMS, OS/2, calls the standard write function; some other systems have particular ways of accessing sockets. If there is an error on the write this function returns SOCKET_ERROR. You can handle errors (in sockerrno) as fatal except for EAGAIN which indicates that the operation would cause a non-blocking socket to block, and EPIPE or ECONNRESET which indicate that the socket was closed at the other end. Treat EWOULDBLOCK as EAGAIN.
