-// Effect control interface
-/////////////////////////////////////////////////
-
-// The effect control interface is exposed by each effect engine implementation. It consists of
-// a set of functions controlling the configuration, activation and process of the engine.
-// The functions are grouped in a structure of type effect_interface_s:
-// struct effect_interface_s {
-// effect_process_t process;
-// effect_command_t command;
-// };
-
-
-// effect_interface_t: Effect control interface handle.
-// The effect_interface_t serves two purposes regarding the implementation of the effect engine:
-// - 1 it is the address of a pointer to an effect_interface_s structure where the functions
-// 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
-// type and return its address as effect_interface_t
