.Sh DESCRIPTION
|
|
The family of DCE 1.1 compliant UUID functions allow applications to operate
|
|
on universally unique identifiers, or UUIDs.
|
|
The
|
|
.Fn uuid_create
|
|
and
|
|
.Fn uuid_create_nil
|
|
functions create UUIDs.
|
|
The
|
|
.Fn uuid_compare ,
|
|
.Fn uuid_equal
|
|
and
|
|
.Fn uuid_is_nil
|
|
functions can be used to test UUIDs.
|
|
To convert from the binary representation to the string representation or
|
|
vice versa, use
|
|
.Fn uuid_to_string
|
|
or
|
|
.Fn uuid_from_string
|
|
respectively.
|
|
A 16-bit hash value can be obtained by calling
|
|
.Fn uuid_hash .
|
|
.Sh RETURN VALUES
|
|
The successful or unsuccessful completion of the function is returned in
|
|
the
|
|
.Fa status
|
|
argument.
|
|
Possible values are:
|
|
.Pp
|
|
.Bl -tag -width ".Dv uuid_s_invalid_string_uuid"
|
|
.It Dv uuid_s_ok
|
|
The function completed successfully.
|
|
.It Dv uuid_s_bad_version
|
|
The UUID does not have a known version.
|
|
.It Dv uuid_s_invalid_string_uuid
|
|
The string representation of an UUID is not valid.
|
|
.It Dv uuid_s_no_memory
|
|
The meaning of the code escaped the writers mind.
