I'm doing some graphics programming and I'm using Vertex pools. I'd like to be able to allocate a range out of the pool and use this for drawing.
Whats different from the solution I need than from a C allocator is that I never call malloc. Instead I preallocate the array and then need an object that wraps that up and keeps track of the free space and allocates a range (a pair of begin/end pointers) from the allocation I pass in.
Much thanks.
in general: you're looking for a memory mangager, which uses a (see wikipedia) memory pool (like the boost::pool as answered by TokenMacGuy). They come in many flavours. Important considerations:
In case of boost::pool, I think the simple segragated storage is worth a look. It will allow you to configure a memory pool with many different block sizes for which a best-match is searched for.
