# GUuid
|
|
|
|
A UUID, or Universally unique identifier, is intended to uniquely
|
|
identify information in a distributed environment. For the
|
|
definition of UUID, see [RFC 4122](https://tools.ietf.org/html/rfc4122.html).
|
|
|
|
The creation of UUIDs does not require a centralized authority.
|
|
|
|
UUIDs are of relatively small size (128 bits, or 16 bytes). The
|
|
common string representation (ex:
|
|
`1d6c0810-2bd6-45f3-9890-0268422a6f14`) needs 37 bytes.
|
|
[func@GLib.uuid_string_is_valid] can be used to check whether a string is a
|
|
valid UUID.
|
|
|
|
The UUID specification defines 5 versions, and calling
|
|
[func@GLib.uuid_string_random] will generate a unique (or rather random)
|
|
UUID of the most common version, version 4.
|
|
|
|
UUID support was added to GLib in version 2.52.
