| 59 | * test__parse_no_sample_id_all - test parsing with no sample_id_all bit set. | |
| 60 | * | |
| 61 | * This function tests parsing data produced on kernel's that do not support the | |
| 62 | * sample_id_all bit. Without the sample_id_all bit, non-sample events (such as | |
| 63 | * mmap events) do not have an id sample appended, and consequently logic | |
| 64 | * designed to determine the id will not work. That case happens when there is | |
| 65 | * more than one selected event, so this test processes three events: 2 | |
| 66 | * attributes representing the selected events and one mmap event. | |
| 67 | * | |
| 68 | * Return: %0 on success, %-1 if the test fails. | |
