# std::experimental::pmr::get_default_resource

From cppreference.com
< cpp‎ | experimental

Defined in header `<experimental/memory_resource>` |  |
memory_resource* get_default_resource(); |  | (library fundamentals TS)

Gets the default memory resource pointer.

The default memory resource pointer is used by certain facilities when an explicit memory resource is not supplied. The initial default memory resource pointer is the return value of `new_delete_resource()`.

This function is thread-safe. Previous call to `set_default_resource` synchronizes with (see std::memory_order) the subsequent get_default_resource calls.

### [edit] Return value

Returns the value of the default memory resource pointer.

### [edit] Exceptions

`noexcept` specification:
noexcept

### [edit] See also

set_default_resource | sets the default `memory_resource` (function) [edit]
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) [edit]
