IOCTL_GENERICUSBFN_CONTROL_STATUS_HANDSHAKE_OUT IOCTL (genericusbfnioctl.h)

This I/O control code (IOCTL) is sent by a user-mode service or application to complete a zero-length control status handshake on endpoint 0 in the OUT direction.

Input buffer

A USBFNPIPEID that specifies the pipe ID of endpoint 0.

Input buffer length

The size of a USBFNPIPEID.

Output buffer

NULL.

Output buffer length

None.

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.
