tresult Steinberg::Vst::Helpers::isProjectState ( IBStream *  state )

inline

Helpers.

Retrieve from a IBStream the state type, here the StateType::kProject return kResultTrue if the state is coming from a project, return kResultFalse if the state is coming from a preset, return kNotImplemented if the host does not implement such feature
