Hello,

I'm trying to create a large array using malloc. I read on msdn that size_t is bounded at 0x7CFFFFFF. (You can assign anything up to 2^32-1, but the malloc will fail.)


I was wondering what was the upper bound of the Intel Compiler. By brute forcing I've got a value of 0x77A5FFE0 (first sucessful malloc). Is this it? Is there a constant somewhere with this magic number?

On a related note, is there any way to push this limit? (Perhaps in assembler, by-passing array fucntions and working directly with the heap?)

Thanks

Microsoft Specific ?>

The type of integer required to hold the maximum size of an array is the size of size_t. Defined in the header file STDDEF.H, size_t is an unsigned int with the range 0x00000000 to 0x7CFFFFFF.
