BINDRESVPORT(3N-BSD)RISC/os Reference Manual BINDRESVPORT(3N-BSD)



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() 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.
