In C++, you don't need these. They are there to allow languages like
Python to use some of the API functions.

Subject: [Csnd] cs_glue.hpp



Hi,
I've been having some trouble with the getters and setters from the 
CsoundMFLTArray class in cs_glue.hpp from interfaces.  These are supposed to 
talk to a software bus, but the .csd locks up when I try to use them.  I may 
not be doing it correctly.
Seems the ChanI opcodes still work fine for the software bus, but this part 
of the glue code by Istvan for the bus doesn't seem to work very well 
nowadays.
Anybody happen to know what might be needed or missing etc.?  The example 
below is incomplete (nothing in the csoundPerformKsmps loop), but it works 
for testing SetValue and GetValue.  The reason I was using the interfaces 
code is because I was working with the java wrappers where it doesn't seem 
working, and I went back to c for a sanity check.  I'm trying on a PC using 
DevC++ using GCC, and Mingw built libs.
Thanks.

                MYFLT* pvalue;
CsoundMYFLTArray(2);
CsoundMYFLTArray csoundMYFLTArray;

if(!result)

int testgetchptr =(csoundGetChannelPtr(csound, &pvalue, "pitch",
                CSOUND_INPUT_CHANNEL | CSOUND_CONTROL_CHANNEL));
                printf("---RESULT of GetChannelPtr: %d\n", testgetchptr); 
//zero is success

              //these guys are causing problems...
              //csoundMYFLTArray.SetValue(0, 400.0);
