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.
