WDF_REQUEST_PARAMETERS_INIT function

Description

[Applies to KMDF and UMDF]

The WDF_REQUEST_PARAMETERS_INIT function initializes a WDF_REQUEST_PARAMETERS structure.

Parameters

Parameters [out]

A pointer to a caller-supplied WDF_REQUEST_PARAMETERS structure.

Remarks

Drivers must call WDF_REQUEST_PARAMETERS_INIT to initialize a WDF_REQUEST_PARAMETERS structure before calling WdfRequestGetParameters.

The WDF_REQUEST_PARAMETERS_INIT function zeros the specified WDF_REQUEST_PARAMETERS structure and sets the structure's Size member.

Examples

The following code example initializes a WDF_REQUEST_PARAMETERS structure and then calls WdfRequestGetParameters.

VOID
MyEvtIoDefault(
    IN WDFQUEUE  Queue,
    IN WDFREQUEST  Request
    )
{
    WDF_REQUEST_PARAMETERS  params;

    WDF_REQUEST_PARAMETERS_INIT(&params);

    WdfRequestGetParameters(
                            Request,
                            &params
                            );
...
}
