//
// Effect control interface handle: effect_handle_t

// of the effect control API for a particular effect are located.
// - 2 it is the address of the context of a particular effect instance.
// A typical implementation in the effect library would define a structure as follows:
// struct effect_module_s {
// const struct effect_interface_s *itfe;
// effect_config_t config;
// effect_context_t context;
// }
// The implementation of EffectCreate() function would then allocate a structure of this
