Infrared IOCTLs
Infrared deprecation warning
Important
The Infrared driver stack is deprecated starting in Windows 10, version 1803 and should no longer be used.
This section describes the specific IOCTLs that the CIRClass driver uses to communicate with CIR Port drivers. Note that support of all IOCTLs is mandatory, unless a given IOCTL specifically indicates that its implementation is optional.
This section includes:
IOCTL_IR_ENTER_PRIORITY_RECEIVE
IOCTL_IR_EXIT_PRIORITY_RECEIVE
