By default on most of the system , Virtual Memory is enabled and malloc/calloc can consume the available space on the HD at Max.

You can allocate as much bytes as type size_t has different values. So in 32-bit application it is 4GB in 64-bit 16 I don't even know how to call that size

All in all you can allocate all memory of machine.
