Hi, my question is about the meanig of qualifiers in combination with typedefs. For example: typedef int function1(); typedef int function2(); ... typedef function1 transition1; typedef function2 transition2; ... int Def_Fun( volatile transition1); int Def_Fun( volatile transition2 const); Specífically, between functionX and transitionX, and before functionX we can add pointer, volatile and const, but what are the meanings of this cualifiers in that places. Someone can help us?. Thanks! -- Departamento de Computaciòn Universidad Nacional de Río Cuarto
