Does this 2 or 3GB limitation only affect 32-bit operating systems? On
my 64-bit Windows, with /LARGEADDRESSAWARE, a simple program can do
close to 64K (65062 for me) 1-byte VirtualAllocs.
Said simple program in case anyone wants to test, excuse the C:
#include <windows.h>
#include <stdio.h>
#define N (64*1024)
void main()
{
int i;
char s[10];
gets(s);
for (i=0; i<N; i++)
{
void *p = VirtualAlloc(NULL, 1, MEM_COMMIT, PAGE_READWRITE);
if (p==NULL)
{
printf("Allocation failed at %d\n", i);
break;
}
*(char*)p = 17;
if (i==0 || i==N-1 || p==NULL)
printf("%p\n", p);
}
gets(s);
}
