All of those types are passed on the stack as 32-bit dwords. No problem.

Yes, but you have to make them outputs from your function. Remember that
assigning to a parameter in Python does not change the parameter from the
caller's point of view:
def FunWithTwoInts( self, inShort, inInt ):
print "got as short:% as int%d" % (inShort, inInt)
return inShort + inInt
If you have multiple OUT parameters, you return a tuple of values.
