-----BEGIN PGP SIGNED MESSAGE-----Hash: SHA1 > With GTK+ you also have the option of inspecting the source code. this is an advantage over closed-source libraries, I agree, but it isn't optimal. Implementation may change over timeand how guarantees that this won't change in the next release? You cannot always download the source code for the simplequestion "should I free it or not?" when such a fact should stay in the (offline) documentation. Besides you first haveto know how is the general structure of the GTK+/Glib/etc/ libraries. I admit that that is not so difficult to realizebut it takes "a lot" of time if it's your first time. I agree with Ian that there are some functions that are not properly documented when it comes to the returned memory.
