i saw an empty struct as struct pref_module; defined in epanpref.h, what is the significance of such structures, i have not come accross such structures. asked 10 Jun '11, 07:25  sagu072 |
One Answer:
It's not an empty struct, it is a struct whose contents are not visible to users of prefs.h. The full structure definition of the structure is in prefs-int.h . Such structures are generally used to make them opaque to the users (so they can't view or change the contents). See the Wikipedia article on such things.
