NAME
       offer_focus - Offers the input focus to a particular object. Allegro game programming library.

SYNOPSIS
       #include <allegro.h>

       int offer_focus(DIALOG *dialog, int obj, int *focus_obj, int force);

DESCRIPTION
       Offers the input focus to a particular object. Normally the function sends the MSG_WANTFOCUS message to query whether the object is willing
       to accept the focus. However, passing any non-zero value as force argument instructs the function to authoritatively set the focus  to  the
       object.
