you should be able to use usrloc's function:
1.15. ul_register_ulcb(type ,callback, param)
The function register with USRLOC a callback function to be called when
some event occures inside USRLOC.
Meaning of the parameters is as follows:
-
*int types* - type of event for which the callback should be called (see
usrloc/ul_callback.h).
-
*ul_cb f* - callback function; see usrloc/ul_callback.h for prototype.
-
*void *param* - some parameter to be passed to the callback each time
when it is called.
