The AtaPortControllerSyncRoutine routine provides synchronized access to data structures that are shared across all channels on a controller.
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.
Syntax
BOOLEAN AtaPortControllerSyncRoutine(
[in] PVOID ChannelExtension,
IDE_HW_DPC CallBackRoutine
);
Parameters
[in] ChannelExtension
A pointer to the channel extension.
CallBackRoutine
A pointer to the routine to call.
Return value
None
Remarks
The miniport driver uses this routine to synchronize access to data structures that are shared across channels on a controller. The miniport driver, however, should use this routine very sparingly.
The ControllerSyncRoutine function pointer is declared in Irb.h as follows:
typedef
VOID
(*IDE_HW_DPC) (
IN PVOID ChannelExtension
);
