GETHOSTID(3)              OpenBSD Programmer's Manual             GETHOSTID(3)

     gethostid, sethostid - get/set unique identifier of current host

     #include <unistd.h>


     sethostid(long hostid);

     sethostid() establishes a 32-bit identifier for the current processor
     that is intended to be unique among all UNIX systems in existence.  This
     is normally a DARPA Internet address for the local machine.  This call is
     allowed only to the super-user and is normally performed at boot time.

     gethostid() returns the 32-bit identifier for the current processor.

     This function has been deprecated.  The hostid should be set or retrieved
     by use of sysctl(3).

     gethostname(3),  sysctl(3),  sysctl(8)

     32 bits for the identifier is too small.

     The gethostid() and sethostid() syscalls appeared in 4.2BSD and were
     dropped in 4.4BSD.
