获取默认内存资源指针。
默认内存资源指针
在未显式提供内存资源时被某些设施使用。初始的默认内存资源指针是
new_delete_resource()
的返回值。
此函数是线程安全的。先前对
set_default_resource
的调用会与后续的
get_default_resource
调用
实现同步
（参见
std::memory_order
）。
返回值
返回默认内存资源指针的值。
参见
设置默认的
memory_resource
(函数) |
|
返回一个静态的、程序级范围的
memory_resource
，该资源使用全局的
operator new
和
operator delete
来分配和释放内存
