#include <allegro.h>

int find_dialog_focus(DIALOG *dialog);

Searches the dialog for the object which has the input focus, returning  an index or -1 if the focus is not set. This is useful if you are calling  do_dialog() several times in a row and want to leave the focus in the  same place it was when the dialog was last displayed, as you can call  do_dialog(dlg, find_dialog_focus(dlg));
