NAME    [Toc]    [Back]

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

LIBRARY    [Toc]    [Back]

     Standard C Library (libc, -lc)

SYNOPSIS    [Toc]    [Back]

     #include <unistd.h>

     long
     gethostid(void);

     void
     sethostid(long hostid);

DESCRIPTION    [Toc]    [Back]

     The 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 a DARPA Internet address for the local machine.
     This call is allowed only to the super-user and is normally performed at
     boot time.

     The gethostid() function 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).

SEE ALSO    [Toc]    [Back]

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

BUGS    [Toc]    [Back]

     32 bits for the identifier is too small.

HISTORY    [Toc]    [Back]

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