First: If you don't know, you don't know. Then you're screwed and C is not going to help. Second: If we cannot figure out how much to allocate before starting to use C (very unlikely), we can always use a callback to Python. Or we can have two C functions, the first determining the amount of allocation, the second doing the computation. > How do you deal with reallocation ? That is platform dependent.

We allocate whatever we need on the Python side, possibly with a callback to Python if that's what we need.
