IOCTL_IR_USER_CLOSE control code
The Infrared driver stack is deprecated starting in Windows 10, version 1803 and should no longer be used.
The IOCTL_IR_USER_CLOSE request is part of basic device communication. This IOCTL is sent from IRCLASS when a user has indirectly closed the port driver. This IOCTL is informational only, enabling the port to do any cleanup that is required when a user closes it.
I/O Status Block

The Status field is set to STATUS_SUCCESS.
The IOCTL_IR_USER_CLOSE IOCTL is available on x86-based and x64-based computers with the Windows Vista operating system.
