There is no "max amount of file handles per process" on Windows.
The C runtime has limitations as you indicated. The Win32 API does not.
File,Socket and other handles to NTOSKRNL objects (GDI is its own beast) are not limited by anything but available memory. some of the used memory is non-pageable in the kernel, and there is a limit to the non-pageable memory (1/8 of RAM, I think), so it's not as simple as RAM/(handlecount*storagecost per handle).
