I have code that works using ctypes.  It doesn't give me that warm feeling.

libc   = ctypes.CDLL("libc.so.6")
class timex(ctypes.Structure):
  _fields_ = [ ("modes",     ctypes.c_uint),
               ("offset",    ctypes.c_long),
               ("freq",      ctypes.c_long),
               ("maxerror",  ctypes.c_long),
               ("esterror",  ctypes.c_long),
...

  libc.ntp_adjtime(ctypes.byref(ntp))

On at least one system, I have to change that 6 to a 7.  It probably works 
without the number,

The other problem is that there is no check that the layout of the struct 
matches what is on the system.

Is there a preprocessor that would automate building the struct?
