UUID(3)                        Libuuid API                       UUID(3)

NAME         top

       uuid - DCE compatible Universally Unique Identifier library

SYNOPSIS         top

       #include <uuid.h>

DESCRIPTION         top

       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         top

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