问题描述
说我有两个进程p1，p2作为我的应用程序的一部分运行.
Say I have two process p1,p2 runnning as a part of my application.
假设p1开始运行时先执行函数f1()，然后f1()调用f2().通过调用f2()，过程p2开始执行
Say p1 is running initially executing function f1() and then f1() calls f2().With the invocation of f2() process p2 starts excuting
我要确认的是:-1)我们有用于不同过程的单独堆栈吗?
What I want to confirm is it that :-1)Do we have seperate stack for different process?
2)我们是否有用于不同进程的单独堆?还是不同的进程共享同一堆?
2)Do we have seperate heap for different process? or do different process share same heap?
3)我们知道，对于32位操作系统，每个进程的虚拟内存大小为4GB.因此，对于每个具有4GB虚拟内存的进程，这4GB也会被分区进入堆，堆栈，文本，数据
3)As we know that for a 32 bit OS do for every process the size of virtual memory is 4GB .So is it that for every process which has 4GB as virtual memory this 4GB is partitioned into heap,stack,text,data
谢谢.
推荐答案
1)是，每个进程都有自己的堆栈.
1) Yes, each process gets its own stack.
2)是的，每个进程都有自己的堆.
2) Yes, each process gets its own heap.
3)我认为您不会获得整个4GB的存储空间.其中一些是保留给内核的东西.
3) I don't think you get the whole 4GB. Some of it is reserved for kernel stuff.
