std::pmr::get_default_resource
std::pmr::get_default_resource
Defined in header <memory_resource> | ||
|---|---|---|
std::pmr::memory_resource* get_default_resource(); | (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.
