DESCRIPTION

The family of DCE 1.1 compliant UUID functions allow applications to operate on universally unique identifiers, or UUIDs. The uuid_create ();
and uuid_create_nil ();
functions create UUIDs. The uuid_compare (,);
uuid_equal ();
and uuid_is_nil ();
functions can be used to test UUIDs. To convert from the binary representation to the string representation or vice versa, use uuid_to_string ();
or uuid_from_string ();
respectively. A 16-bit hash value can be obtained by calling uuid_hash (.);

The uuid_enc_le ();
and uuid_enc_be ();
functions encode a binary representation of a UUID into an octet stream in little-endian and big-endian byte-order, respectively. The destination buffer must be pre-allocated by the caller, and must be large enough to hold the 16-octet binary UUID. These routines are not part of the DCE RPC API. They are provided for convenience.

The uuid_dec_le ();
and uuid_dec_be ();
functions decode a UUID from an octet stream in little-endian and big-endian byte-order, respectively. These routines are not part of the DCE RPC API. They are provided for convenience.

RETURN VALUES

The successful or unsuccessful completion of the function is returned in the Fa status argument. Possible values are:

uuid_s_ok: The function completed successfully.
uuid_s_bad_version: The UUID does not have a known version.
uuid_s_invalid_string_uuid: The string representation of an UUID is not valid.
uuid_s_no_memory: The meaning of the code escaped the writers mind.
