View the official Win32 API referenceNo description available.
This I/O control code (IOCTL) is sent by a user-mode service or application to issue an IN direction transfer on the endpoint that corresponds to the specified pipe ID in the input buffer. A zero-length packet is automatically appended after the data in the output buffer is successfully sent and the transfer payload size is a multiple of the endpoint's maximum packet size. This should be used on the last I/O request that corresponds to a Universal Serial Bus (USB) transfer.
A USBFNPIPEID that specifies the ID of the pipe to conduct the transfer on.
The size of a USBFNPIPEID.
The data to send to the host.
The size of the output buffer in bytes.
Irp->IoStatus.Status is set to STATUS_SUCCESS if the request is successful. Otherwise, Status to the appropriate error condition as a NTSTATUS code.
If this I/O control code (IOCTL) is being called synchronously, set the lpOverlapped parameter to NULL. If this IOCTL is called asynchronously, assign the lpOverlapped parameter to a pointer to an OVERLAPPED structure that contains a handle to an event object. The event objects signal when the operation is completed.
The return value is a BOOL value that indicates success or failure of the operation. TRUE indicates success, FALSE otherwise.
