allegro_message(3) Allegro manual allegro_message(3)NAMEallegro_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 Allegro 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 dif‐
ferences by reducing any accented characters to 7-bit ASCII approxima‐
tions. Example:
if (allegro_init() != 0)
exit(1);
if (init_my_data() != 0) {
allegro_message("Sorry, missing game data!\n");
exit(2);
}
