Hi! I am writting actually a memory manager. Everything works great:
  
#include "memory_manager.h"
#include "iostream.h"

CMemoryManager MG(2*1024*1024);	// reserve 2 MB for the beginning


class z
{
public:
	int a1;
	int a2;
	int a3;
	int a4;
	int a5;
	int a6;
	int a7;
	int a8;
};

void main()
{
	cout << "Free memory: " << MG.GetFreeMemory() << " - Total memory: " << MG.GetTotalMemory() << endl;
	z* a;

	a = (z*)MG.Allocate(sizeof(z));

	cout << "Free memory: " << MG.GetFreeMemory() << " - Total memory: " << MG.GetTotalMemory() << endl;

	a->a5 = 5;

	cout << a->a5 << endl;

	....
	....
	....
}
  
Now I want to replace the standard new with a own functions, which uses MG.Allocate(). How can i do this? Thanks, Austrian Coder

Thanks!

I have now maked my Memory manager to a singleton -> gMemoryMng.
And this is my new operator:

void* ::operator new(size_t size)
{
return gMemoryMng->Allocate(size);
}

And it works great
