DLL Calling Conventions, Need Help

[IEC]

Hey everyone,

need some help here...

How do I setup the 'call library function node' for a function in a dll which is called as such:

(in C)  bool get_dxdy_pos (signed short * pDXManual, signed short * pDYManual);

I'm not sure how I pass a pointer in labview, and as for the bool return I can just use an unsigned short int right?

Thanks

Hi IEC,

As attachement you will find how the setup should be in LabVIEW, hope this helps

Sorry, I meant to ask what do I connect to the block terminals?  If it's a pointer, can I connect a control? or what?

thanks

Whether it is a pointer or not, first af all the setup of the call library node function must be done, and if you want to pass a value

to the dll, you can connect a control, if you get a value from the dll, you will become a indicator.

You will find a lot of examples at ...\National Instruments\LabVIEWx.x\examples\dll
