A UUID, or Universally unique identifier, is intended to uniquely identify information in a distributed environment. For the definition of UUID, see RFC 4122.
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.
The UUID specification defines 5 versions, and calling
g_uuid_string_random() will generate a unique (or rather random)
UUID of the most common version, version 4.
Parses the string
and verify if it is a UUID.
The function accepts the following syntax:
simple forms (e.g.
Note that hyphens are required within the UUID string itself, as per the aforementioned RFC.
gchar * g_uuid_string_random (
Generates a random UUID (RFC 4122 version 4) as a string. It has the same randomness guarantees as GRand, so must not be used for cryptographic purposes such as key generation, nonces, salts or one-time pads.
