NAME

std::pmr::get_default_resource - std::pmr::get_default_resource

Synopsis

Defined in header <memory_resource>
std::pmr::memory_resource* get_default_resource() noexcept; (since C++17)

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 std::pmr::new_delete_resource.

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

Return value

Returns the value of the default memory resource pointer.
