AtaPortRequestTimer function

Description

The AtaPortRequestTimer routine requests a timer callback.

Note The ATA port driver and ATA miniport driver models may be altered or unavailable in the future. Instead, we recommend using the Storport driver and Storport miniport driver models.

Parameters

ChannelExtension [in]

A pointer to the channel extension.

CallBackRoutine

A pointer to the timer routine.

TimerValue [in]

Time interval in units of microseconds.

Return value

None

Remarks

The AtaPortRequestTimer routine informs the ATA port driver that it must call the timer routine that is pointed to by TimerRoutine in the number of microseconds indicated by TimerValue.

The ATA port driver passes a pointer to the channel extension to the timer routine.
