# alert(3alleg)

Displays a popup alert box. Allegro game programming library.

## 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).
