In a lot of languages callbacks are really common. You might call a function 
with another function as an argument and at some point
in the body of the called function the callback function gets called. You said 
this is done with pointers in C... not sure how
common this is there so bear with me.

# This is (psuedo-code) based on javascript where callbacks are really common
because it's asynchronous (i.e. you often need a callback to be notified when 
the function you've called is complete). First two function definitions:
