[ctypes-users] python callind delphi

[Donald L. D. <dl...@en...>]

I was given a  lib_xx.so  which I believe was written in Delphi, and
ask to prepare a Python wrapper.  One thing lead to another which
eventually lead to ctpyes, which doesn't seem to do the job either.
I an testing with:


#!/usr/bin/python2
#
#  Lets make ctypes work with libBitLink
#
from ctypes import cdll
import os, sys

libBL = cdll.LoadLibrary("/home/dld/bitlink/BitLinkLib/libBitLink.so")

libBL.BS_Init()
f = libBL.BS_Open("TTY:/dev/ttys1")
print f

libBL.BS_Send(f, "?")
print libBL.BS_Count(f)


BS_Open always returns 0, whether I supply a valid device or make
multiple calls on the same device.  BS_Send apparently isn't
effective either, as Count always reveals that zero bytes are
being returned in response.

Am I missing something?  Suggestions?
