man init_dialog () - Low level initialisation of a dialog. Allegro game programming library.
NAME
init_dialog - Low level initialisation of a dialog. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
DIALOG_PLAYER *init_dialog(DIALOG *dialog, int focus_obj);
DESCRIPTION
This function provides lower level access to the same functionality as do_dialog(), but allows you to combine a dialog box with your own program control structures. It initialises a dialog, returning a pointer to a player object that can be used with update_dialog() and shutdown_dialog(). With these functions, you could implement your own version of do_dialog() with the lines:
DIALOG_PLAYER *player = init_dialog(dialog, focus_obj);
while (update_dialog(player))
;
return shutdown_dialog(player);
