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

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.
