/** Establish the known port to listen for network connections.
|
|
|
|
The listen routine places the port into a state that enables connection
|
|
attempts. Connections are placed into FIFO order in a queue to be serviced
|
|
by the application. The application calls the ::accept routine to remove
|
|
the next connection from the queue and get the associated socket.

|
|
@param [in] s Socket file descriptor returned from ::socket.
|
|
|
|
@param [in] backlog backlog specifies the maximum FIFO depth for the connections
|
|
waiting for the application to call ::accept. Connection attempts
|
|
received while the queue is full are refused.
|
|
|
|
@return This routine returns zero (0) if successful or -1 when an error occurs.
|
|
In the case of an error, ::errno contains more details.
