This header is part of the experimental library.

Classes

Defined in namespace std::experimental::pmr
memory_resource	an abstract interface for classes that encapsulate memory resources (class)
synchronized_pool_resource	a thread-safe memory_resource for managing allocations in pools of different block sizes (class)
unsynchronized_pool_resource	a thread-unsafe memory_resource for managing allocations in pools of different block sizes (class)
monotonic_buffer_resource	a special-purpose memory_resource that releases the allocated memory only when the resource is destroyed (class)
polymorphic_allocator	an allocator that supports run-time polymorphism based on the memory_resource it is constructed with (class template)
resource_adaptor	adapts an allocator into a memory_resource (alias template)

Functions

Defined in namespace std::experimental::pmr
Comparison
operator==operator!=	compare two memory_resources (function)
operator==operator!=	compares two allocators (function template)
Global memory resources
new_delete_resource	returns a static program-wide memory_resource that uses the global operator new and operator delete to allocate and deallocate memory (function)
null_memory_resource	returns a static memory_resource that performs no allocation (function)
Default memory resource
get_default_resource	gets the default memory_resource (function)
set_default_resource	sets the default memory_resource (function)
