cache_chunklist Class
Defines a block allocator that allocates and deallocates memory blocks of a single size.
template <std::size_t Sz, std::size_t Nelts = 20> class cache_chunklist
Parameters

Description |
|---|---|
Sz |
The number of elements in the array to be allocated. |
Remarks
This template class uses operator new to allocate chunks of raw memory, suballocating blocks to allocate storage for a memory block when needed; it stores deallocated memory blocks in a separate free list for each chunk, and uses operator delete to deallocate a chunk when none of its memory blocks is in use.
Each memory block holds Sz bytes of usable memory and a pointer to the chunk that it belongs to. Each chunk holds Nelts memory blocks, three pointers, an int and the data that operator new and operator delete require.
