why you are using bool here? it is not a C standard. would it be
possible to use int? or gboolean

if these are not used, just remove them

the same here

why you cast here? just change to %d

this i didn't get. why you are not using structure directly, but
introducing pointer to it instead?

should it be static?

this shall be defined via -D in Makefile
