It is unspecified if or under what circumstances this operation will result in a call to deallocate() on the upstream memory resource. Exceptions Throws nothing. See also               deallocates memory deallocate (public member…

std::experimental::pmr::unsynchronized_pool_resource::do_allocate – std::experimental::pmr::unsynchronized_pool_resource::do_allocate Synopsis virtual void* do_allocate(std::size_t bytes, std::size_t alignment); (library fundamentals TS) Allocates storage. If the pool selected for a block of size bytes is unable to satisfy the request from its internal data structures, calls allocate() on the upstream memory resource to obtain memory. If the size requested is larger than what the…
