How to achieve function overloading in C?

Question

Is there any way to achieve function overloading in C? I am looking at simple functions to be overloaded like

foo (int a)  
foo (char b)  
foo (float c , i         


        

Answer 1

There are few possibilities:

1. printf style functions (type as an argument)
2. opengl style functions (type in function name)
3. c subset of c++ (if You can use a c++ compiler)
