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.
