uuid_is_nil- determines if a UUID is a nil-valued UUID.
boolean32 uuid_is_nil( uuid_t *uuid, unsigned32 *status);
- Specifies a UUID to test for nil value.
- Returns the status code from this routine. The status code indicates whether the routine completed successfully, or if not, why not.
Possible status codes and their meanings include:
The uuid_is_nil() routine determines whether the specified UUID is a nil-valued UUID. This routine yields the same result as if an application did the following:
- called the uuid_create_nil() routine
- called the uuid_equal() routine to compare the returned nil-value UUID to the UUID specified in the uuid argument.
If successful, returns one of the following constants:
- The uuid argument is a nil-valued UUID.
- The uuid argument is not a nil-valued UUID.
