SYNOPSIS    [Toc]    [Back]

       #include <sys/types.h>

DESCRIPTION    [Toc]    [Back]

       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.
