allegro_message(3) Allegro manual allegro_message(3) NAME allegro_message - Used mainly to show error messages to users. Allegro game programming library. SYNOPSIS #include <allegro.h> void allegro_message(const char *text_format, ...); DESCRIPTION Outputs a message, using a printf() format string. Usually you want to use this to report messages to the user in an OS independent way when some Al- legro subsystem cannot be initialised. But you must not use this function if you are in a graphic mode, only before calling set_gfx_mode(), or after a set_gfx_mode(GFX_TEXT). Also, this function depends on a system driver being installed, which means that it won't display the message at all on some platforms if Allegro has not been initialised correctly. On platforms featuring a windowing system, it will bring up a blocking GUI message box. If there is no windowing system, it will try to print the string to a text console, attempting to work around codepage differences by reducing any accented characters to 7-bit ASCII approximations. Example: if (allegro_init() != 0) exit(1); if (init_my_data() != 0) { allegro_message("Sorry, missing game data!\n"); exit(2); } SEE ALSO allegro_init(3), install_allegro(3), set_uformat(3) Allegro version 4.4.3 allegro_message(3)
