IOCTL_WINUSB_GET_CURRENT_FRAME_NUMBER control code
[This documentation is preliminary and is subject to change.]
The IOCTL_WINUSB_GET_CURRENT_FRAME_NUMBER control code sends a request to get the current frame number for an isochronous request.
To perform this operation, call the DeviceIoControl function with the following parameters.
AssociatedIrp.SystemBuffer points a caller-allocated WINUSB_FRAME_NUMBER structure that the request populates with the current frame number and a performance count.
The USB stack sets Irp->IoStatus.Status to STATUS_SUCCESS if the request is successful. Otherwise, the USB driver stack sets Status to the appropriate error condition, such as STATUS_INVALID_PARAMETER or STATUS_INSUFFICIENT_RESOURCES.
