Description
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.
Functions
g_uuid_string_is_valid ()
gboolean
g_uuid_string_is_valid (const gchar *str);
Parses the string str
and verify if it is a UUID.
The function accepts the following syntax:
Note that hyphens are required within the UUID string itself,
as per the aforementioned RFC.
Returns
TRUE if str
is a valid UUID, FALSE otherwise.
Since: 2.52
g_uuid_string_random ()
gchar *
g_uuid_string_random (void);
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.
Returns
A string that should be freed with g_free().
