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.
