将多少堆栈存储器分配给程序 [英] How many stack memories will be allocated to a program

问题描述

我有一个程序，它有4个项目作为依赖项（这意味着它必须加载4个dll来运行该程序）。操作系统是否分配4个堆栈内存或者只为整个程序分配1个堆栈内存以及如何将为程序分配多少堆栈内存大小？

I have a program which have 4 projects as dependency for that (that means it has to load 4 dlls to run that program) .Does the OS allocates 4 stack memories or only 1 stack memory will be allocated for whole program and how much stack memory size will be allocated for the program?

推荐答案

取决于：堆栈与应用程序运行的每个线程相关联：所以如果它只启动一个线程 - 它是主线程 - 并且不再做任何事情，然后它将获得一个且只有一个堆栈。



这不是严格准确的（因为有）一个单独的堆栈，供您的应用程序可以与之交互的设备驱动程序使用，但它足够准确，适用于99.99％的应用程序！



实际大小堆栈在构建时是可变的（参见 MSDN：/ F标志 [ ^ ]）也可能因应用程序运行的环境而异。它在运行时不会改变。

Depends: a stack is associated with each thread that the application runs: so if it only ever starts one thread - it's main thread - and doesn't do anything to start any more, then it will get one and only one stack.

That's not strictly accurate (as there is a separate stack that is used by device drivers that your app may interface with and such like) but it's accurate enough for 99.99% of applications!

The actual size of the stack is variable at build time, (See MSDN: /F flag[^]) and also may vary depending on the environment your app runs in. It does not change at run time.
