Hello,
i've got a problem with pointers in the following function which i want
to use:
I16 __stdcall DO_ReadPort (U16 CardNumber, U16 Port, U32 *Value)
The function is supposed to read out the status of a digital port of
analog digital interface card.
I got this function from Dask.h which came with the card. The relevant
lines concerning this function are the following:
typedef short I16;
typedef unsigned short U16;
typedef unsigned long U32;
I16 __stdcall DO_ReadPort (U16 CardNumber, U16 Port, U32 *Value)
I tried to implement this function into python:
# I16 __stdcall DO_ReadPort (U16 CardNumber, U16 Port, U32 *Value);
ReadOPort = dask.DO_ReadPort
ReadOPort.argtypes = [c_ushort, c_ushort, c_ulong]
ReadOPort.restype = c_short
I can't handle the pointer "Value" which should be an unsigned long
pointer. I'd be very happy, if u could give me a hint how to implement
this pointer into python.
Thanks a lot
Carlo and Pierre
