WindowsError: exception: access violation

[Sathish S]

Benjamin thanks for replying. i'm not using the python that comes with
cygwin. Its the regular python 2.7.2
To add more info
I'm opening up a zip file within the DLL. The zip file is located in the
same directory.
arg1 is the file name
arg2 is zip password

Thanks,
Sathish
