A tutorial on how to write LADSPA code in C allready exists. I have never
done it. I got 50% of the way through a simple plugin before I got bored
of typing:
port_descriptors = (LADSPA_PortDescriptor *)calloc(3,
sizeof(LADSPA_PortDescriptor));
ampDescriptor->PortDescriptors =
(const LADSPA_PortDescriptor *)port_descriptors;
...
Then I decided it was a job for software.
I don't use C++ for religious reasons ;) But, I suspect it could be a good
choice for LADSPA plugins, the CMT set are C++ IIRC.
OTOH all the stuff I write would be applicable, its just that do do it in
raw C you would have to write a lot of routine setup code too.
