I have this program build before, and exe for windows. There's this function I want to execute when I am done modifying it. I saw a way of calling a function of such using Asmjit. So I am new to this asmjit, and I want to know if it's possible to copy the existing function, using embed method found in x86Assembler class and then call the function from within another scope or in a DLL injected into the process of the existing application.

What I have tried:

Don't know what to try, since I am new to that API and the documentation is not readily available.
