EVT_UDECX_USB_DEVICE_DEFAULT_ENDPOINT_ADD callback function (udecxusbdevice.h)

  • Article

The USB device emulation class extension (UdeCx) invokes this callback function to request the client driver to create the default control endpoint on the virtual USB device.

Syntax

EVT_UDECX_USB_DEVICE_DEFAULT_ENDPOINT_ADD EvtUdecxUsbDeviceDefaultEndpointAdd;

NTSTATUS EvtUdecxUsbDeviceDefaultEndpointAdd(
  [in] UDECXUSBDEVICE UdecxUsbDevice,
  [in] PUDECXUSBENDPOINT_INIT UdecxEndpointInit
)
{...}

Parameters

[in] UdecxUsbDevice

A handle to the UDE device object for which the client driver creates the default endpoint. The driver created this object in a previous call to UdecxUsbDeviceCreate.

[in] UdecxEndpointInit

A pointer to an UDECXUSBENDPOINT_INIT structure that the client driver retrieved in the previous call to UdecxUsbSimpleEndpointInitAllocate.

Return value

If the operation is successful, the callback function must return STATUS_SUCCESS, or another status value for which NT_SUCCESS(status) equals TRUE.
