在标准C中没有办法做到这一点。但是，你的编译器

可能提供一种方法。编译器特定的问题在

comp.lang.c中是偏离主题的，所以请在专门针对您的编译器的小组中询问。

它可能是，但这里无关紧要。就标准C而言，

不是堆栈。 C标准并没有规定动态

分配是如何在'封面'下管理的。

大家好！

有没有人知道，如果可以在整个执行期间确保C程序的最大堆栈使用量吗？

如果你的平台使用了一个堆栈，而且之前的海报已经提到了

，那么这样做是不可能的，那么它通常是可能的。


*在程序开始时，取一个自动的

变量的地址并存储它。

*找出堆栈在你的架构上的增长方式。

*在程序的任何一点，调用一个创建一个

自动变量的函数，取它的地址。将它与之前的

存储的地址进行比较。


这不能保证工作。要找到***的方法，请在

上查询特定于体系结构的新闻组。

Hi everyone!

Does anyone know, if it is possible to meassure the maximum stack usage of
a C program throughout it''s entire execution?

There is no way to do this in standard C. However, your compiler
might provide a way. Compiler-specific questions are off-topic in
comp.lang.c, so please ask in a group dedicated to your compiler.

It may be, but it is irrelevant here. As far as standard C is concerned, there
is no such thing as a ''stack''. The C standards don''t dictate how dynamic
allocations are to be managed ''under the covers''.

Hi everyone!

If your platform uses a stack, and as previous posters have mentioned
it is not gauranteed to do so, then it''s normally possible.

* At the beginning of the program take the address of a automatic
variable and store it.
* Find out which way the stack grows on your architecture.
* At any point in the program, call a function that creates an
automatic variable, take it''s address. Compare it to the previously
stored address.

This is not gauranteed to work. To find the best way to do it ask on
an architecture specific newsgroup.
