Member Function Documentation

handleVstHostCallbackAvailable()

virtual void juce::VSTCallbackHandler::handleVstHostCallbackAvailable ( std::function< VstHostCallbackType > &&  callback )

inlinevirtual

This is called once by the VST plug-in wrapper after its constructor.

You can use the supplied function to query the VST host.

References juce::ignoreUnused().

handleVstManufacturerSpecific()

virtual pointer_sized_int juce::VSTCallbackHandler::handleVstManufacturerSpecific ( int32  index, pointer_sized_int  value, void *  ptr, float  opt  )

pure virtual

This is called by the VST plug-in wrapper when it receives unhandled vendor specific calls from the host.

handleVstPluginCanDo()

virtual pointer_sized_int juce::VSTCallbackHandler::handleVstPluginCanDo ( int32  index, pointer_sized_int  value, void *  ptr, float  opt  )

inlinevirtual

This is called by the VST plug-in wrapper when it receives unhandled plug-in "can do" calls from the host.
