恰好那个程序结束后没有释放的内存是什么？ [英] What happens to memory that is not freed after end of program?

问题描述

复制：<一href=\"http://stackoverflow.com/questions/654754/what-really-happens-when-you-dont-free-after-malloc\">What如果你不这样做的malloc后免费真正发生？

比方说，例如：

int main()
{
  char* test = new char[50000];
  return 0;
}

该程序已完成后发生了分配的内存呢？是否得到立即释放其他应用程序？或许一段时间后？或者，也许它是输给了系统永远不会消失？抑或是被换到磁盘再也没有回到内存？或者，也许完全不同的东西？

What happens to the allocated memory after the program had finished? Does it get freed for other applications immediately? Or perhaps after some time? Or maybe it's lost to the system forever? Or does it get swapped to the disk never to return to RAM? Or maybe something completely different?

我想知道的3大操作系统的会发生什么：的Windows（XP及以上，如果有任何差异），在Linux，Mac OS X

I would like to know what happens on the major 3 OS's: Windows (XP and up, if there are any differences), Linux, Mac OS X.
