gethostid(3N)           (BSD Compatibility Package)           gethostid(3N)

NAME
     gethostid, sethostid - get/set unique identifier of current host

SYNOPSIS
     /usr/ucb/cc [flag ...] file ... -lucb

     #include <unistd.h>

     long gethostid(void);

     int sethostid(long hostid);

DESCRIPTION
     gethostid returns the 32-bit identifier for the current host, which
     should be unique across all hosts. This number is usually taken from
     the CPU board's ID PROM.

     sethostid establishes a 32-bit identifier for the current processor,
     which is intended to be unique among all Reliant UNIX systems in
     existence. This is normally a DARPA Internet address for the local
     machine. This call is allowed only to the superuser and is normally
     performed at boot time.

     This routine resides in libucb.
