object_message - Sends a message to an object and returns the answer. Allegro
game programming library.
#include <allegro.h>
int object_message(DIALOG *dialog, int msg, int c);
Sends a message to an object and returns the answer it has generated. Remember
that the first parameter is the dialog object (not a whole array) that you
wish to send the message to. For example, to make the second object in a
dialog draw itself, you might write:
object_message(&dialog[1], MSG_DRAW, 0);
The function will take care of scaring and unscaring the mouse if the message is
MSG_DRAW.
