UUID(3)                       Programmer's Manual                      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(1).

       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
       <https://tools.ietf.org/html/rfc4122>.
