In the code I am writing I need foo(int, char*) and foo(int, int) functions.
If I was coding this in C++ I would use templates. Is there any equivalent for C? Or should I use void pointers? How?
You can’t do that.
In C there are no overloads, one function, one name, you’ll need to use a type that supports all your needs, e.g. (void *)
Either that or do a
foo_int(int,int)and afoo_char(int, char*)
