Determining Stack Space with Visual Studio

Question

I\'m programming in C in Visual Studio 2005. I have a multi-threaded program, but that\'s not especially important here.

How can I determine (approximately) how muc

Answer 1

The stack doesn't work the way you expect it too. The stack is a linear sequence of pages, the last (top) one of which is marked with a page guard bit. When this page is touched, the guard bit is removed, and the page can be used. For further growth, a new guard page is allocated.

Hence, the answer you want is where the gaurd page is allocated. But the technique you propose would touch the page in question, and as a result it would invalidate the very thing you're trying to measure.

The non-invasive way to determine if a (stack) page has the guard bit is via VirtualQuery().
