!!NAME


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


__#include __


__long int gethostid(void);
int sethostid(long int__
''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).
!!CONFORMING TO

not define these functions, but ISO/IEC 9945-1:1990 mentions
them in B.4.4.1. SVr4 includes __gethostid__ but not
__sethostid__.
