Just to add to the complications, on 32-bit platforms, off_t can be either
64 bits or 32 bits, depending on whether a C program is compiled with
-D_FILE_OFFSET_BITS=64 or not. This causes all kinds of aliasing of POSIX
routines to the appropriate variants of the underlying libc routine names.
With ctypes, you have to directly access the underlying routine names,
unless you implement some kind of equivalent aliasing scheme on top.
