uuid

UUID(3) 							    Libuuid API 							   UUID(3)

NAME

       uuid - DCE compatible Universally Unique Identifier library

SYNOPSIS

       #include <uuid/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.

       libuuid is part of the util-linux package since version 2.15.1 and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
