Thread: interesting problem

Check out the BFD library documentation. You should be able to override functions calls, etc. using it.

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
