SYNOPSIS

#include <unistd.h>
long gethostid (void);
void sethostid (long hostid);

DESCRIPTION

The sethostid ();
function 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.

The gethostid ();
function 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).
