IOCTL_WINUSB_WRITE_ISOCH_PIPE control code
[This documentation is preliminary and is subject to change.]
The IOCTL_WINUSB_WRITE_ISOCH_PIPE control code sends a request to write data to an isochronous OUT endpoint.
To perform this operation, call the DeviceIoControl function with the following parameters.
AssociatedIrp.SystemBuffer points to a WINUSB_ISOCH_WRITE structure that specifies the user-mode address and size of a buffer that the application previously registered by calling WinUsb_RegisterIsochBuffer. The structure also specifies the starting frame number for the transfer resulting from this request.
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.
