C++ detect Apple headphone buttons on Windows - windows

Question

BACKGROUND INFORMATION:
I've been trying to detect a button click from Apple headphone. The headphone is connected to MacBook Pro that is running Windows. Its not virtual machine. It is running windows normally with a complete windows driver from Apple through Boot Camp.
The headphone is a standard Apple headphone consisted of three buttons: a volume up, volume down, middle buttons and a Mic.
When I am using Mac Os, If the volume up button is presses on the ear phone, Mac Os would increase its volume by one. It also decreases its volume when the voulume down button is pressed on the ear phone.
Standard ear/headphone uses three conductive pins to receive(L/R speakers only) signals while the apple version is using four conductive pins to receive(L/R speakers) and send(buttons) signals. This headphone was made for iPhone but I was surprised when it worked on Mac Os.
This made me believe that the MacBook Pro hardware is built to support this four conductive pins earphone. It works on Mac Os but NOT on Windows. My goal is to develop a tiny software that will allow the apple headphone to function on Windows running on Apple hardware.
I know how to increase Windows volume using C++ and Win32 API but I am stuck on the part where I actually have to detect the button click from the headphone.
QUESTION:
1) what ways can I detect the Input(button clicks) from the headphone?
It looks like this person here was able to read it. He only did it while running on Mac Os
Detect hardware headphone presses in mac
2) If I compile the code this person got working on Mac OS as a DLL file and then call the function while running Windows, will it work?
3) Do I need to make my own driver to get this to work?
4) The code below is from the link I posted above. What windows API function, class is equivelent to the follwoing Mac Os code below?
id array = [[DDHidDevice allDevices] filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:#"productName == \"Apple Mikey HID Driver\""]];
DDHidDevice *mic = [array count] ? [array objectAtIndex:0] : nil;
// it isn't a keyboard
NSLog(#"%#", mic.primaryUsage);
assert(mic.usage==1 && mic.usagePage==12);
THINGS I'VE TRIED:
1) I tried using GetLastInputInfo() with LASTINPUTINFO from Windows API to sniff any hardware input but failed miserably. It worked on keyboard and mouse but nothing else.
2) I also tried to use RAWINPUTDEVICE to read a low level input from hardware but it only worked on keyboards, mouse and joystick input. It didn't detect the headphone button press.
I am running out of ideas. Anyone got any solution?
NOTE: This is not a duplicate question as I am asking how to do this on Windows not Mac.
