Arguments
socket
A descriptor of an open socket created by %SS_SOCKET. (i4)
backlog
(optional) Specifies the maximum number of pending connections (1 to 5) that may be queued on the stream socket at any given time. If not passed, the default is 5. (n)
Discussion
%SS_LISTEN creates a queue for pending connection requests on socket. Connections can then be accepted with %SS_ACCEPT or %SS2_ACCEPT. If a connection request arrives with the queue full, the client receives a time-out.
%SS_LISTEN is used by stream socket server applications only.
