bindresvport(3R)                  NFS 5.4.2                 bindresvport(3R)


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 sockaddrin *sin;

DESCRIPTION
       Bindresvport(3R) is used to bind a socket descriptor to a privileged
       Internet Protocol (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(3X)) 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.

SEE ALSO
       rcmd(3X).
