The AcxTargetCircuitFormatRequestForMethod formats a WDFREQUEST as an ACX method request to be used on specified circuit target.

Syntax

NTSTATUS AcxTargetCircuitFormatRequestForMethod(
  ACXTARGETCIRCUIT        TargetCircuit,
  WDFREQUEST              Request,
  PACX_REQUEST_PARAMETERS Params
);

Parameters

TargetCircuit

An ACXTARGETCIRCUIT handle. For more information about ACX objects, see Summary of ACX Objects.

Request

A WDFREQUEST handle described in Summary of Framework Objects. For general information about WDF requests, see Creating Framework Request Objects.

Params

Remarks

A WDFREQUEST is a driver created I/O requests. Framework-based drivers process each I/O request by calling framework request object methods. For more information, see Framework Request Objects.

Example


    ACX_REQUEST_PARAMETERS      params;
    WDFREQUEST                  req;
    ACXTARGETCIRCUIT            targetCircuit;

...

    //
    // Format a WDF request as an ACX method request for the ACX circuit target.
    //
    status = AcxTargetCircuitFormatRequestForMethod(targetCircuit, req, &params);
