[Scilab-users] Windows 10 VS 2015 example under ilib_build fails pvApiCtx undeclared identifier

[Fredrik Blomqvist]

Hi Clement,

thanks for answering.

You are correct, the pvApiCtx global define available in Scilab 5 no more

Ah, yes I will, but at the moment I still don't know where the bug is
except it seems some documentation is missing (or it's a combination with
something I have misunderstood).

In a sentence, you should add a variable `void* pvApiCtx` on each gateway

This I found in the documentation, so if I were doing a gateway, then I
don't think anything is really missing in the documentation. The problem is
I'm running Scilab from my C++ exe file (Scilab Engine instead of Gateway
if I understood the naming correctly). In short I did this from my program
(using Scilab 5.5.2):

   1. Start up the scilab instance: StartScilab()
   2. Call my script: SendScilabJob()
   3. Read back some variables after the script is done:
   readNamedMatrixOfDouble( pvApiCtx, ...)
   4. TerminateScilab()

But up until number 3 above, "pvApiCtx" wasn't needed. And I've read some
other discussion on this mailing list that you shouldn't mix the old 5.2
stack-style with the new 6.X C++ API style, but that feels exactly what I'm
doing!? So I'm guessing I'm actually reading back my variables wrong, but I
didn't find any documentation of another way to do it? Sending NULL on
pvApiCtx makes the program work (which I found in an example), but is it
really the right 6.X way to do it in?

Thanks for any hints
