IOCTL_IR_ENTER_PRIORITY_RECEIVE control code
The Infrared driver stack is deprecated starting in Windows 10, version 1803 and should no longer be used.
The IOCTL_IR_ENTER_PRIORITY_RECEIVE request puts the IR receiver into learning mode. This learning can be a 10-foot learn (parse-and-match) or a 2-foot learn from the learning receiver.
This request is sent to prepare the port to enter Priority Receive mode. While the device is in Priority Receive mode, all IOCTL_IR_RECEIVE requests should be starved and IOCTL_IR_PRIORITY_RECEIVE requests should be completed.
Irp->AssociatedIrp.SystemBuffer points to an IR_ENTER_PRIORITY_RECEIVE_PARAMS structure that contains parameters for the Priority Receive operation.
I/O Status Block
The Information field is set to zero.
The Status field is set to STATUS_SUCCESS or an appropriate error status.
The IOCTL_IR_ENTER_PRIORITY_RECEIVE IOCTL is available on x86-based and x64-based computers with the Windows Vista operating system.
