Answer 1

Yes, you can::

call("functionwithasmcode.asm");

This function will have to:

1. Invoke the assembler and linker - create the dynamic link library.
2. Depending on the system you need to load this library (for example in Linux by calling the dlopen function, in Windows LoadLibrary).
3. Find your function in the library, assign to function pointer (it is also OS dependant for example in Linux dlsym, windows GetProcAddress)
4. call the function using the function pointer from the point 3.
