    S\bSe\bet\bth\bho\bos\bst\bti\bid\bd() 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.

    G\bGe\bet\bth\bho\bos\bst\bti\bid\bd() 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).

S\bSE\bEE\bE A\bAL\bLS\bSO\bO
    sysctl(2),  gethostname(3),  sysctl(8).

B\bBU\bUG\bGS\bS
    32 bits for the identifier is too small.

    The g\bge\bet\bth\bho\bos\bst\bti\bid\bd() and s\bse\bet\bth\bho\bos\bst\bti\bid\bd() syscalls appeared in 4.2BSD and were
    dropped in 4.4BSD.
