NAME
       bindresvport - bind a socket to a privileged IP port

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

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

DESCRIPTION
       bindresvport()  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.

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