Hello, I'm new to boost memory pool. I have two questions: 1) My program has multiple iterations. In each iteration, I need to allocate chunks(objects) from a pool. I don't need to allocate array of chunks. I don't free objects until the end of an iteration. Then what is the most efficient way to do that? I wrote the following code, but I'm not sure it is right. boost::pool<> p(sizeof(MyType)); for (...) { ... // many calls to p.malloc(); ... p.release_memory(); // Is it OK??? } Also, I was wondering, to improve locality, how to reuse the memory in the next iteration, instead of deallocating/allocating memory again and again. 2) How to inquiry a pool to know have many objects have been allocated from the pool? For example, if malloc() 2 times, free() 1 time, then the count is 1. Does boost pool have this interface? Thanks! -- Junchao Zhang
