Declared in `<bdlma_pool.h>`

Create a memory pool that returns blocks of contiguous memory of the specified `blockSize` (in bytes) for each `allocate` method invocation. Optionally specify a `growthStrategy` used to control the growth of internal memory chunks (from which memory blocks are dispensed). If `growthStrategy` is not specified, geometric growth is used. Optionally specify `maxBlocksPerChunk` as the maximum chunk size if `growthStrategy` is specified. If geometric growth is used, the chunk size grows starting at `blockSize`, doubling in size until the size is exactly `blockSize * maxBlocksPerChunk`. If constant growth is used, the chunk size is always `blockSize * maxBlocksPerChunk`. If `maxBlocksPerChunk` is not specified, an implementation‐defined value is used. Optionally specify a `basicAllocator` used to supply memory. If `basicAllocator` is 0, the currently installed default allocator is used. The behavior is undefined unless `1 <= blockSize` and `1 <= maxBlocksPerChunk`.
