Call Library Function returning a pointer to doubles

[Michael Vetsch]

Hi,

Say, I have a DLL which exports function

int getdata(int numdatapoints, double * data)

I would like to use a Call Library function to call getdata and getting the
data (* data) into a Labview array of type double. Is this supported by the
Call Library function, or do I have to use a CIN function?

Thanks,

Michael

In the meantime I found out, that you can specifiy a parameter as Array with
format Array Data Pointer and additionally defining the Dimension. But what
do you do when the dimension changes from one call to the other. Is there a
way to define the Dimension dynamically during the execution of the VI
containing the Library Call function?

Thanks,

Michael

Problem solved. I found an application note on NI's Web page. I've got it
working.
