This function cancels a queued bus request as generated by SDBusRequest.

Syntax

BOOLEAN SDCancelBusRequest(
  PSD_BUS_REQUEST pRequest
);

Parameters

  • pRequest
    [in, out] Pointer to an SD_BUS_REQUEST structure to be cancelled.

Return Value

Returns a BOOLEAN return value that indicates whether or not the request has been successfully cancelled.

Remarks

If cancellation of the request was successful, the Status field of the SD_BUS_REQUEST structure will be set to SD_API_STATUS_CANCELED.

A driver must wait for the request to complete with a cancelled status. When a bus request is completed, its completion callback will be invoked. Only in the completion callback is it safe to free the bus request.
