!!CONFORMING TO
Single Unix, 4.4BSD, POSIX 1003.1g draft. The listen(2) function call first appeared in 4.2BSD.
!!BUGS
-If the socket is of type __AF_INET__, and the backlog argument is greater than the constant __SOMAXCONN__ (128 in Linux 2.0 & 2.2), it is silently truncated to __SOMAXCONN__. Don’
t rely on this value in portable applications since BSD (and some BSD-derived systems) limit the backlog to 5.

!!DISCUSSION
To use listen(2), you need a socket fd created with socket(2), and you probably also want to bind(2) it to a local port. So the sequence of actions you want are probably socket(2), bind(2) (optional, but recommended), listen(2), select(2) (optional), accept(2), close(2)
