Standard C Library Functions                        gethostid(3C)



NAME
     gethostid - get an identifier for the current host

SYNOPSIS
     #include 

     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.
