AtaPortControllerSyncRoutine function (irb.h)

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
  );

Requirements

Requirement Value
Target Platform Desktop
Header irb.h (include Ata.h, Irb.h)
