IOCTL_GENERICUSBFN_TRANSFER_OUT IOCTL

Description

This I/O control code (IOCTL) is sent by a user-mode service or application to issue an OUT direction transfer on the endpoint that corresponds to the specified pipe ID in the input buffer.

Parameters

Input buffer

A USBFNPIPEID that specifies the ID of the pipe to conduct the transfer on.

Input buffer length

The size of a USBFNPIPEID.

Output buffer

The data received from the host.

Output buffer length

The size of the output buffer in bytes.

Input/output buffer

Input/output buffer length

Status block

Irp->IoStatus.Status is set to STATUS_SUCCESS if the request is successful. Otherwise, Status to the appropriate error condition as a NTSTATUS code.

Remarks

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.
