UUID(3)                           Libuuid API                          UUID(3)

NAME
       uuid - DCE compatible Universally Unique Identifier library

SYNOPSIS
       #include <uuid.h>

DESCRIPTION
       The  UUID  library  is  used to generate unique identifiers for objects
       that may be accessible beyond the local system.  This library generates
       UUIDs  compatible  with  those  created by the Open Software Foundation
       (OSF) Distributed Computing Environment (DCE) utility uuidgen.

       The UUIDs generated by this library can be reasonably  expected  to  be
       unique  within  a system, and unique across all systems.  They could be
       used, for instance, to generate unique HTTP cookies across multiple web
       servers  without communication between the servers, and without fear of
       a name clash.

CONFORMING TO
       This library generates UUIDs compatible with  OSF  DCE  1.1,  and  hash
       based UUIDs V3 and V5 compatible with RFC-4122.
