Question

I like the convenience of NSMutableArray but sometimes you just need to drop down to good ole C-arrays. Like when you are feeding interleaved vertex arrays to OpenGL.

What is the fastest way of copying the contents of an NSMutableArray to a C-array?

Yah, I realize this bit shuffling introduces inefficiency but I’d like to see if I can sneak by with this approach without taking a hit in frame rate.

Cheers,
Doug

id *buffer = malloc(numberOf_ItemsIWant_ToFetch * sizeof(id));
[myArray getObjects:buffer range:rangeOfItems]
