GETHOSTID(3C) Standard C Library Functions 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.
