UUID(3) Programmers 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 [34mRFC-4122
<https://tools.ietf.org/html/rfc4122>.

REPORTING BUGS
For bug reports, use the issue tracker at [34mhttps://github.com/util-linux/util-linux/issues.
AVAILABILITY
The libuuid library is part of the util-linux package since version 2.15.1. It can be downloaded from [34mLinux
[34mKernel Archive <https://www.kernel.org/pub/linux/utils/util-linux/>.
