How to get Monitor Handle from Index or Name? - windows

Question

A C++ version (How can I get an HMONITOR handle from a display device name?) has no solution provided (at least in my circumstances that require non-OOP code such as in AutoIt).
I'm adapting an AutoIt script that uses WinAPI functions to support multi-monitor Windows 7+ systems. I can provide either monitor/device Name or it's Index, but some functions require an HMONITOR handle instead.
I cannot get the HMONITOR by Window or by pixel or point, which would be quite easy. No, I need to get the handle from name or index only, and I need a non-OOP solution (ideally AutoIt & WinAPI calls but non-OOP pseudo-code would be fine).

The function below returns an array of the following structure:
| hMonitor | xPosMonitor | yPosMonitor | widthMonitor | heightMonitor |
| 0x00010001 | 0 | 0 | 1366 | 768 |
| 0x0001024 | 1366 | -236 | 1920 | 1080 |
Code:
#include-once
#include <Array.au3>
#include <WinAPIGdi.au3>
Func _getMonitorInfos()
Local $aPosition, $aMonitorData = _WinAPI_EnumDisplayMonitors()
If IsArray($aMonitorData) Then
ReDim $aMonitorData[$aMonitorData[0][0] + 1][5]
For $i = 1 To $aMonitorData[0][0] Step 1
$aPosition = _WinAPI_GetPosFromRect($aMonitorData[$i][1])
For $j = 0 To 3 Step 1
$aMonitorData[$i][$j + 1] = $aPosition[$j]
Next
Next
Return $aMonitorData
EndIf
EndFunc
Global $aMonitorData = _getMonitorInfos()
_ArrayDisplay($aMonitorData)
hMonitor value is contained by the array $aMonitorData[1][1].
