listen
listen(3SOCKET) Sockets Library Functions listen(3SOCKET)
NAME
listen - listen for connections on a socket
SYNOPSIS
cc [ flag ... ] file ... -lsocket -lnsl [ library ... ]
#include <sys/types.h>
#include <sys/socket.h>
int listen(int s, int backlog);
DESCRIPTION
To accept connections, a socket is first created with socket(3SOCKET), a backlog for incoming connections is specified with listen() and
then the connections are accepted with accept(3SOCKET). 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 will receive an error with an indication of ECONNREFUSED for AF_UNIX sock-
ets. If the underlying protocol supports retransmission, the connection request may be ignored so that retries may succeed. For AF_INET
and AF_INET6sockets, the TCP will retry the connection. If the backlog is not cleared by the time the tcp times out, the connect will fail
with ETIMEDOUT.
RETURN VALUES
A 0 return value indicates success; -1 indicates an error.
ERRORS
The call fails if:
EBADF The argument s is not a valid file descriptor.
ENOTSOCK The argument s is not a socket.
EOPNOTSUPP The socket is not of a type that supports the operation listen().
