std::experimental::pmr::get_default_resource 💅

okay bestie, this is the tea from the C++ Standard Libary manual — yes, it really says “Libary,” and we are not editing the manual’s spelling, we’re just here for the lore. The star of this page is std::experimental::pmr::get_default_resource.

🎀 NAME 🎀

std::experimental::pmr::get_default_resource — std::experimental::pmr::get_default_resource

no cap, the name is listed twice up top. That’s just the manual being extra, iykyk.

💫 Synopsis 💫

Defined in header <experimental/memory_resource>:

memory_resource* get_default_resource() noexcept;

(library fundamentals TS)

Gets the default memory resource pointer. That pointer is the main character for certain facilities when an explicit memory resource is not supplied — like, it’s the fallback bestie. The initial default memory resource pointer is the return value of new_delete_resource().

This function is thread-safe, periodt. A previous call to set_default_resource synchronizes with (see std::memory_order) the subsequent get_default_resource calls.

🌸 Return value 🌸

Returns the value of the default memory resource pointer. yep, that’s the whole return-value vibe 💖

• sets the default memory_resource — set_default_resource (function).
• returns a static program-wide memory_resource that uses the global operator new and operator delete to allocate and deallocate memory — new_delete_resource (function).
