bindresvport — bind a socket to a privileged IP port

Synopsis

#include <sys/types.h>
#include <netinet/in.h>
int bindresvport( 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.
