IOCTL_GENERICUSBFN_CONTROL_STATUS_HANDSHAKE_IN IOCTL (genericusbfnioctl.h)
This I/O control code (IOCTL) is sent by a user mode service or application to request a zero-length control status handshake on endpoint 0 in the IN 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.
