Hi, what is callback in ZbPersistNotifyRegister and ZbSetLogging functions and how I can use it?

[Maxim Shylo]

bool

ZbPersistNotifyRegister(struct ZigBeeT *zb, void (*callback)(struct ZigBeeT *zb, void *cbarg), void *cbarg);

void

ZbSetLogging(struct ZigBeeT *zb, uint32_t mask,

  void (*func)(struct ZigBeeT *zb, uint32_t mask, const char *hdr, const char *fmt, va_list argptr));
