| 26 | * \section sleep_test_sec Scope of the Test |
| 27 | * |
| 28 | * This tests: |
| 29 | * - whether pj_thread_sleep() works. |
| 30 | * - whether pj_gettimeofday() works. |
| 31 | * - whether pj_get_timestamp() and friends works. |
| 32 | * |
| 33 | * API tested: |
| 34 | * - pj_thread_sleep() |
| 35 | * - pj_gettimeofday() |
| 36 | * - PJ_TIME_VAL_SUB() |
| 37 | * - PJ_TIME_VAL_LTE() |
| 38 | * - pj_get_timestamp() |
| 39 | * - pj_get_timestamp_freq() (implicitly) |
| 40 | * - pj_elapsed_time() |
| 41 | * - pj_elapsed_usec() |
