EVT_UFX_DEVICE_TEST_MODE_SET callback function

The client driver's implementation to set the test mode of the function controller.

Syntax

EVT_UFX_DEVICE_TEST_MODE_SET EvtUfxDeviceTestModeSet;

void EvtUfxDeviceTestModeSet(
  UFXDEVICE ,
  ULONG 
)
{...}

Parameters

arg1

arg2

Return Value

This callback function does not return a value.

Remarks

The client driver for the function host controller registers its EVT_UFX_DEVICE_TEST_MODE_SET implementation with the USB function class extension (UFX) by calling the UfxDeviceCreate method.

The client driver indicates completion of this event by calling the UfxDeviceEventComplete method.

Examples

EVT_UFX_DEVICE_TEST_MODE_SET UfxDevice_EvtDeviceTestModeSet;

VOID
UfxDevice_EvtDeviceTestModeSet (
    _In_ UFXDEVICE UfxDevice,
    _In_ ULONG TestMode
    )
/*++

Routine Description:

    EvtDeviceTestModeSet handler for the UFXDEVICE object.

    Handles a set test mode request from the host.  Places the controller into 
    the specified test mode.

Arguments:

    TestMode - Test mode value.  See Section 7.1.20 of the USB 2.0 specification for definitions of 
               each test mode.
