GETHOSTID(3C)GETHOSTID(3C)NAME
gethostid - get an identifier for the current host
SYNOPSIS
#include <unistd.h>
long gethostid(void);
DESCRIPTION
The gethostid() function returns the 32-bit identifier for the current
host. If the hardware capability exists, this identifier is taken from
platform-dependent stable storage; otherwise it is a randomly generated
number. It is not guaranteed to be unique.
If the calling thread's process is executing within a non-global zone
that emulates a host identifier, then the zone's emulated 32-bit host
identifier is returned.
