If you attach the XV_KEY_DATA to the button it will work.

     panel = (Panel)xv_create(frame,	PANEL,
 			     NULL);
     printf("The string still is: \"%s\"\n",string);
     xv_create(panel,	PANEL_BUTTON,
 	      PANEL_LABEL_STRING,	"Verify & Quit",
 	      PANEL_NOTIFY_PROC,	button_cb,
 	      XV_KEY_DATA,	1,	string,
 	      NULL);
     xv_main_loop(frame);
     exit(0);
 }
 
 void button_cb(item,event)
 Panel_item	item;
 Event		*event;
 {
     printf("The string now is \"%s\"\n",(char*)xv_get(item,XV_KEY_DATA,1));
     xv_destroy_safe(frame);
 }
