Before the declaration of functions like FT_ListDevices() that use the
PVOID type, you need to have a typemap defined for PVOID, e.g.
%typemap(in) PVOID {
/* code to convert Python input to a PVOID */
}
FT_STATUS FT_ListDevices(
PVOID pvArg1,
PVOID pvArg2,
DWORD Flags
);
Having said that, it is criminal that the library's author(s) have
overloaded the FT_ListDevices() function in such an insane way. I agree
with the other reply to your post, which recommended writing a little
wrapper library of some kind around this C API and then using SWIG or
Boost to wrap that instead.
Hope this helps,
Lyle
