* queue of pending connections, creates a new connected socket, and
* returns a new file descriptor referring to that socket.
* The newly created socket is not in the listening state.
* The original socket sd is unaffected by this call.
* The argument sd is a socket that has been created with socket(),
* bound to a local address with bind(), and is listening for
* connections after a listen(). The argument addr is a pointer
* to a sockaddr structure. This structure is filled in with the
* address of the peer socket, as known to the communications layer.
* The exact format of the address returned addr is determined by the
* socket's address family. The addrlen argument is a value-result
* argument: it should initially contain the size of the structure
* pointed to by addr, on return it will contain the actual
* length (in bytes) of the address returned.
*
* Input Parameters:
* sd socket descriptor (handle)
