To pass a pointer to a member function

Question

I have an class with instance functions (or methods?). From within an instance, I try to pass pointers to those functions to a library. The library expects static functions

Answer 1

What you are trying to do is not possible. This is glut's fault actually.

The thing is this:

• glut wants to call a function, without giving it data,
• You want your function to use some data,

which are conflicting needs. I believe glut decided you can safely use global variables.

So, one solution is to use static functions, with static data. Or a better solution would be to switch to SDL.
