Hi,
I'm looking at porting some plugins I've developed to Csound 7. In a few 
of these I use csound->plugin_deinit(this) which causes the struct's 
deinit() method to be called on deinitialisation.
However this isn't in the current plugin.h. Does anyone know if deinit() 
would be called automatically now if it exists - or if this has to be 
handled some other way?

Thanks!

Hi Richard,

in Csound 7 you only need to define a deinit(), no need to register it anymore.

Hi,
Great, thank you - I suspected that may be the case.
