Guess you meant: can a recursive function call predefined functions? Answer: sure, why not.
Predefined functions are built-in functions that perform standard operations and that generally do not depend on any classes. A predefined void function is simply a predefined function that has no return value. An example of a predefined void function is the abort() function which typically has the following signature: void abort(void);
That won't happen, you have to have a predefined putpixel (or something like that) function.
