== Description

Return the address of a contiguous block of memory of the specified `size` (in bytes) according to the alignment strategy specified at construction. If `size` is 0, no memory is allocated and 0 is returned. If the allocation request exceeds the remaining free memory space in the external buffer supplied at construction, use memory obtained from the allocator supplied at construction.
