array

There's this instance variable in my objective-c class:

ALuint source;

I need to have an mutable array of OpenAL Sources, so in this case probably I need a mutable C-array.

But how would I create one? There are many questions regarding that:

1) How to create an mutable C-array?

2) How to add something to that mutable C-array?

3) How to remove something from that mutable C-array?

4) What memory management pitfalls must I be aware of? Must i free() it in my -dealloc method?

And yes, I think this is something for the nice community wiki...
