You have the choice (just a cast pb) : 

1. void create_file_select(GtkWidget *w, gpointer *chosen1) {
	info *thechosen = (info *) chosen1;
	....}

or directly :

2. void create_file_select(GtkWidget *w, info *choser1) {
	....
	chosen1->selected...
	}

I personnaly use 2. but I am not a professional :)
