sethostid — get/set unique
identifier of current host
sethostid() function establishes a
32-bit identifier for the current processor that is intended to be unique
among all UNIX systems in existence. This is normally an Internet address
for the local machine. This call is allowed only to the superuser 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(2).
sethostid() system calls first appeared in
4.1cBSD and were dropped in
32 bits for the identifier is too small.
