15 // Overview: |
|
16 // Test delta timers. |
|
17 // API Information: |
|
18 // CDeltaTimer. |
|
19 // Details: |
|
20 // - Create a delta timer and queue a number of timed events with different time intervals. |
|
21 // The callback functions of the timed events perform various actions: |
|
22 // - Requeuing itself |
|
23 // - Cancelling the previous or next timer |
|
24 // - Doing nothing |
|
25 // - Stopping the active scheduler |
|
26 // - Verifies the timed events are run correctly and orderly |
|
27 // - The callback for each timed event increments a counter each time they are run |
|
28 // - The counters are checked to check how many times each callback has been called |
|
29 // Platforms/Drives/Compatibility: |
|
30 // All. |
