How do I know what signal triggered a callback?

well, I am learning that a selection one of radio button group in a
menu creates two callbacks: one to unselect the current selection and
one to select the new one. 

I am using GNOMEUIINFO_RADIOITEM_DATA to create the radio button and
attach automatically the callback.

The question is, can I know what signal triggered the callback?  If
so, how? 

thanks in advance for any help,
