GETHOSTID(3)		 BSD Library Functions Manual		  GETHOSTID(3)

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

SYNOPSIS
     #include <unistd.h>

     long
     gethostid(void);

     void
     sethostid(long hostid);

DESCRIPTION
     Sethostid() establishes a 32-bit identifier for the current processor
     that is intended to be unique among all UNIX systems in existence.	 This
     is	normally a DARPA Internet address for the local	machine.  This call is
     allowed only to the super-user and	is normally performed at boot time.

     Gethostid() returns the 32-bit identifier for the current processor.

     This function has been deprecated.	 The hostid should be set or retrieved
     by	use of sysctl(3).

SEE ALSO
     gethostname(3), sysctl(3),	sysctl(8).

BUGS
     32	bits for the identifier	is too small.

HISTORY
     The gethostid() and sethostid() syscalls appeared in 4.2BSD and were
     dropped in	4.4BSD.

4.2 Berkeley Distribution	 June 2, 1993	     4.2 Berkeley Distribution
