================= Memory Allocation

[memory_allocation]

This section describes classes and functions related to memory allocation.

Allocators

The oneAPI Threading Building Blocks (oneTBB) library implements several classes that meet the allocator requirements from the [allocator.requirements] ISO C++ Standard section.

Memory Resources

Starting from C++17, the standard library provides a std::pmr::polymorphic_allocator class that allocates memory from a supplied memory resource (see the [mem.poly.allocator.class] ISO/IEC 14882:2017 section). Class std::pmr::memory_resource is an abstract interface for user-side implementation of different allocation strategies. For details, see the [mem.res.class] ISO/IEC 14882:2017 standard section.

oneTBB provides a set of std::pmr::memory_resource implementations.
