Remarks

Drivers must call WDF_REQUEST_COMPLETION_PARAMS_INIT to initialize a WDF_REQUEST_COMPLETION_PARAMS structure before calling WdfRequestGetCompletionParams.

The WDF_REQUEST_COMPLETION_PARAMS_INIT function zeros the specified WDF_REQUEST_COMPLETION_PARAMS structure and sets the structure's Size member. It also sets the structure's Type member to WdfRequestTypeNoFormat.
