bindresvport(3)						       bindresvport(3)

NAME
       bindresvport - Bind a socket to a privileged IP port

SYNOPSIS
       #include <sys/types.h> #include <netinet/in.h> #include <unistd.h>

       int bindresvport(
	       int sd,
	       struct sockaddr_in *sin );

DESCRIPTION
       The  bindresvport()  function  is used to bind a socket descriptor to a
       privileged IP port, that is, a port number in  the  range  0-1023.  The
       routine	returns	 0  if	it is successful, otherwise -1 is returned and
       errno set to reflect the cause of the error. This routine differs  with
       rresvport() (see rcmd(3)) in that this works for any IP socket; whereas
       rresvport() only works for TCP.

       Only root can bind to a privileged port; this call will	fail  for  any
       other users.
