58 | * test__parse_no_sample_id_all - test parsing with no sample_id_all bit set. | |
59 | * | |
60 | * This function tests parsing data produced on kernel's that do not support the | |
61 | * sample_id_all bit. Without the sample_id_all bit, non-sample events (such as | |
62 | * mmap events) do not have an id sample appended, and consequently logic | |
63 | * designed to determine the id will not work. That case happens when there is | |
64 | * more than one selected event, so this test processes three events: 2 | |
65 | * attributes representing the selected events and one mmap event. | |
66 | * | |
67 | * Return: %0 on success, %-1 if the test fails. | |
