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

       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.
