What is the purpose of ANYSIZE_ARRAY in ?

Question

What\'s the purpose of ANYSIZE_ARRAY, located in WinNT.h?

I see an MSDN blog post about it from 2004 but it doesn\'t make sense to me.

Answer 1

From this page:

In C, a variable-size array is declared as a[1] or a[ANYSIZE_ARRAY], where ANYSIZE_ARRAY is defined as 1. Then it is used as if it were bigger.
