|
|---|
| 38 | * The IPRT timer API provides a simple abstraction of recurring and one-shot callback timers.
|
|---|
| 39 | *
|
|---|
| 40 | * Because of the great variation in the native APIs and the quality of
|
|---|
| 41 | * the service delivered by those native APIs, the timers are operated
|
|---|
| 42 | * on at best effort basis.
|
|---|
| 43 | *
|
|---|
| 44 | * All the ring-3 implementations are naturally at the mercy of the scheduler,
|
|---|
| 45 | * which means that the callback rate might vary quite a bit and we might skip
|
|---|
| 46 | * ticks. Many systems have a restriction that a process can only have one
|
|---|
| 47 | * timer. IPRT currently makes no efforts at multiplexing timers in those kind
|
|---|
| 48 | * of situations and will simply fail if you try to create more than one timer.
|
|---|
| 49 | *
|
|---|
| 50 | * Things are generally better in ring-0. The implementations will use interrupt
|
|---|
| 51 | * time callbacks wherever available, and if not, resort to a high priority
|
|---|
| 52 | * kernel thread.
