What is a “callback” in C and how are they implemented?
...k:
typedef void (*event_cb_t)(const struct event *evt, void *userdata);
Now, define a function that is used to register a callback:

This is what code would look like that registers a callback:
static void my_event_cb(const struct event *ev...
