c++ - 提升单例池 release_memory 与 purge_memory

Question

我在哪里可以找到Boost Singleton Poolpurge_memory和in之间的区别？release_memory在这里它说：

Singleton Usage是每个Pool是一个具有静态持续时间的对象的方法；也就是说，直到程序退出它才会被销毁。可以共享具有 Singleton Usage 的池对象；因此，单例用法也意味着线程安全。由具有 Singleton Usage 的 Pool 对象分配的系统内存可以通过release_memory或释放purge_memory。

单击页面上的几个链接会导致该页面。

在那里您可以阅读以下内容：

t.release_memory()  bool    t must be ordered. Frees every memory block that doesn't have any
                allocated chunks. Returns true if at least one memory block was freed.

t.purge_memory()    bool    Frees every memory block. This function invalidates any pointers
                previously returned by allocation functions of t. Returns true if at
                least one memory block was freed.
