Hi
Check out the ctypes example I just pushed.

The part you're concerned with:

libh = ctypes.c_ushort(0)  
ret = focas.cnc_allclibhndl3(
    b"127.0.0.1",
    8193,
    10,
    ctypes.byref(libh),
)

from fwlib.

Hi strangesast
My code works now.
And C parameter such as unsigned short,long int doesn't need ctypes to convert directly,correct?
Thanks

yeah from the docs it looks like None, int, bytes, and str are converted to corresponding ctypes but you can override those by adding an _as_parameter_ attr to an argument or add the argtypes or restype attrs to the wrapped function

the cnc_allclibhndl3 seems to require char* (not wchar*) so it fails when using str as the first argument, for example
