pointers

In C, I have declared a memory area like this:

int cells = 512;
int* memory = (int*) malloc ((sizeof (int)) * cells);

And I place myself more or less in the middle

int* current_cell = memory + ((cells / 2) * sizeof (int));

My question is, while I increment *current_cell, how do I know if I reached the end of the allocated memory area?
