How to make Functions of AutoHotkey in c++

[Parama]

I want to create a function that has the same function as the commands in Auto Hot Key.
So I analyzed the parts where the function of open-source was implemented, but I don't know what to do. structure is too complex.
Not only is the command's own function implemented, but it also includes others. because open source is script language.
For example, I wanna function that is identical to 'send' command in AutoHotkey.
There are parts in which the function is implemented, but it is written too complex for the simple command as 'send'.
The implementation of 'send' function in open-source is written in script2.cpp. but "ResultType Line::Send(,,){...};" it says, I don't think the class is necessary because I only need one command like 'send'. So I used 'void' as return-type in my code
But I just want to create a function that is identical to the function of the command.
How can I do what I want to do? I'd appreciate it if you could help me.
