    Lightbulb Pls help : Function declaration outside structure definition.

    Dear all,

    I am following an opensource project and came across following code segment
    Code:
    struct MState
    {
      uint8_t sVert;
      uint8_t sHorz;
      static uint8_t event;
      void init(){sVert=sHorz=0;};
      
      void checkExit(uint8_t event,bool immediate=false);
      //!/ schltet horiz weiter zum naechsten menu. 
      //!/ entry    initialisiert, 
      //!/ key_exit schaltet in zwei stufen zurueck zuerst sub=0, dann popmenu
      void checkChain( uint8_t curr, MenuFuncP *menuTab, uint8_t size);
      //!/ schltet vertik weiter zum naechsten submenu. 
      //!/ entry    initialisiert, 
      //!/ keine reaktion auf exit
      uint8_t checkVert( uint8_t maxVert);
      //!/ schltet horiz weiter zum naechsten subsubmenu. 
      //!/ entry    initialisiert, 
      //!/ keine reaktion auf exit
      uint8_t checkHorz( uint8_t myVert, uint8_t maxHoriz);
    };
    uint8_t MState::event;
    what i dont understand is since the function "MState::event" is not declared in the structure itself why its declared outside. ? assuming that "MState::event" refers to a function not the "static uint8_t event" variable declared in the structure.

    If this is a common practice please let me know the exact name for this kind of work..

    Thanks a lot in advance and I'm really sorry if I'm driving you guys nuts asking silly question because of my lack of knowledge.

    This is C++, not C. We'll have it moved (don't post it there, someone will move it).

    Hope is the first step on the road to disappointment.
