LISTEN(2)										LISTEN(2)

NAME
       listen - listen for connections on a socket

SYNOPSIS
       listen(s, backlog)
       int s, backlog;

DESCRIPTION
       To  accept  connections, a socket is first created with socket(2), a willingness to accept
       incoming connections and a queue limit for incoming connections are  specified  with  lis-
       ten(2),	and  then  the	connections are accepted with accept(2).  The listen call applies
       only to sockets of type SOCK_STREAM or SOCK_SEQPACKET.

       The backlog parameter defines the maximum length the queue of pending connections may grow
       to.   If  a connection request arrives with the queue full the client may receive an error
       with an indication of ECONNREFUSED, or, if the underlying  protocol  supports  retransmis-
       sion, the request may be ignored so that retries may succeed.

RETURN VALUE
       A 0 return value indicates success; -1 indicates an error.

ERRORS
       The call fails if:

       [EBADF]		   The argument s is not a valid descriptor.

       [ENOTSOCK]	   The argument s is not a socket.

       [EOPNOTSUPP]	   The socket is not of a type that supports the operation listen.

SEE ALSO
       accept(2), connect(2), socket(2)

BUGS
       The backlog is currently limited (silently) to 5.
