The accept() call extracts the first connection request on<br /> the queue of pending connections, creates a new socket with the same<br /> properties of s, and allocates a new file descriptor for the socket. If<br /> no pending connections are present on the queue, accept() blocks the caller until a connection is<br /> present. The accepted socket may not be used to accept more connections. The<br /> original socket s remains open.<br /> <br /> The argument addr is a result parameter that is filled in with the address of the connecting entity as known to the communications layer, which for the Spectranet is only sockaddr_in. Assembly language programmers may use the [[getsockinfo]] call to fill a block of memory with the address information.<br /> <br /> It is possible to [[poll]] a socket for the purposes of doing an accept() by selecting it for read.<br /> <br /> == Return values ==<br /> <br /> On success, the C accept() call returns 0, and on error, -1. The assembly language call returns with the carry flag reset on success, and carry set on error with the A register set to the error code.<br /> <br /> [[Category:Spectranet]]</div>
