NAME

       gethostid, sethostid - get or set the unique identifier of the current host

SYNOPSIS

       #include <unistd.h>

       long gethostid(void);
       int sethostid(long hostid);

DESCRIPTION

       Get  or	set  a unique 32-bit identifier for the current machine.  The 32-bit identifier is intended to be unique among all UNIX systems in
       existence. This normally resembles the Internet address for the local machine, as returned by  gethostbyname(3),  and  thus  usually  never
       needs to be set.

       The sethostid call is restricted to the superuser.

       The hostid argument is stored in the file /etc/hostid.

RETURN VALUE

       gethostid returns the 32-bit identifier for the current host as set by sethostid(2).
