-Routine Description:
-
- The WaitForTick() function waits for the number of ticks specified by
- TickNumber from a known time source in the platform. If TickNumber of
- ticks are detected, then EFI_SUCCESS is returned. The actual time passed
- between entry of this function and the first tick is between 0 and
- TickPeriod 100 nS units. If you want to guarantee that at least TickPeriod
- time has elapsed, wait for two ticks. This function waits for a hardware
- event to determine when a tick occurs. It is possible for interrupt
- processing, or exception processing to interrupt the execution of the
- WaitForTick() function. Depending on the hardware source for the ticks, it
- is possible for a tick to be missed. This function cannot guarantee that
- ticks will not be missed. If a timeout occurs waiting for the specified
- number of ticks, then EFI_TIMEOUT is returned.
-
-Arguments:
-
- This - The EFI_METRONOME_ARCH_PROTOCOL instance.
- TickNumber - Number of ticks to wait.
-
-Returns:
-
- EFI_SUCCESS - The wait for the number of ticks specified by TickNumber
- succeeded.
