std::pmr::get_default_resource

STD：：PMR：：GET[医]违约[医]资源

Defined in header ​​
std::pmr::memory_resource* get_default_resource(​(since C++17)

获取默认内存资源指针。

大默认内存资源指针当未提供显式内存资源时，某些设施使用。的返回值为初始默认内存资源指针。std::pmr::new_delete_resource...

这个函数是线程安全的.。前一次打电话到std::pmr::set_default_resource与...同步28%见std::memory_order%29std::pmr::get_default_resource打电话。

返回值

返回默认内存资源指针的值。

例外

noexcept规格：

noexcept

另见

set_default_resource (C++17)sets the default std::pmr::memory_resource (function)
new_delete_resource (C++17)returns a static program-wide std::pmr::memory_resource that uses the global operator new and operator delete to allocate and deallocate memory (function)
