alert(3)                        Allegro manual                        alert(3)

NAME
       alert - Displays a popup alert box. Allegro game programming library.

SYNOPSIS
       #include <allegro.h>

       int alert(const char *s1, *s2, *s3, const char *b1, *b2, int c1, c2);

DESCRIPTION
       Displays a popup alert box, containing three lines of text (s1-s3), and
       with either one or two buttons. The text for these buttons is passed in
       `b1' and `b2' (`b2' may be NULL), and the keyboard shortcuts in `c1'
       and `c2' as ASCII value. Example:

          if (!exists(CONFIG_FILE))
             alert(CONFIG_FILE, "not found.", "Using defaults.",
                   "&Continue", NULL, 'c', 0);

RETURN VALUE
       Returns 1 or 2 depending on which button was clicked. If the alert is
       dismissed by pressing ESC when ESC is not one of the keyboard
       shortcuts, it treats it as a click on the second button (this is
       consistent with the common "Ok", "Cancel" alert).
