    Check out the BFD library documentation. You should be able to override functions calls, etc. using it.
    If you understand what you're doing, you're not learning anything.

    I've played around with it before to print function names referenced by pointer:
    Code:
    typedef void (*timer_handler)(uint32_t timer_id, void *data);
    
    struct timer
    {
      uint32_t        timer_id;     // Hopefully unique timer id
      struct timeval  when;         // Absolute time when handler is called
      timer_handler   what;         // Handler callback
      enum timer_type type;         // TT_ONCE or TT_RECUR
      struct timeval  period;       // Period for recurring timers
      void           *data;         // User data passed to callback
      struct timer   *next;
    };
    Code:
    +timer
    timer_id sec         usec        handler             data
