Hi.

I posted a while back about finding a way to get callbacks triggered
by Csound events, as opposed to constant values being output, and I
finally came across Csound.SetOutputValueCallback(). This function
appears to be inherited by the CppSound class, which is what I've been
using for several reasons. I have a pretty involved setup using
CppSound with CsoundPerformanceThread, and I also prefer to pass the
options/orchestra/score directly to the object as a string, rather
than saving them as a .csd file and passing the name of the file.
When I call SetOutputValueCallback() with the CppSound class, I get
segmentation faults. I tried overriding it by defining it (even with a
different function name) to specifically call the Csound class
function, but apparently I don't know how to do that right.
I want to have that one function work like it does with the Csound
class, and everything else from the CppSound class. Can anyone tell me
how I can do that?

Thanks.
-Chuckk

Hi,

Are you setting the callback before Csound has started running? Also,
are you sure you are using the right arguments to the callback
function?

Cheers,
Andres

 Hi Andres,

Thanks for the suggestions. Here is an example .py that crashes with a
seg fault for me. It gets as far as defining the function and creating
a CppSound instance, but the SetOutputValueCallback function crashes.
I'm using the same argument that works with the same function under
the Csound class.

Hi again.

Could someone else please just try running the script I attached to
the last message?
Thanks.

Crashes here as well,
I've never used the callback in python,
maybe Victor needs to chime in on this.

This might be something to do with the way Swig works. I have supplied  
the interface for that method by extending the
Csound class in the python interface file. Maybe that extension only  
applies to the Csound class and not to CppSound ?
I need to investigate it.

OK, thanks for checking.
It seems strange if the function is inherited without being altered in
the CppSound class; makes me wonder if it's not the function itself
but some of the class attributes it accesses?

This is because of the way I have designed the interface. It needs a  
data object that is only built for the python module. For this to happen
the constructor needs to be inlined in the header file, which is now.
