NAME
textprintf_centre_ex - Formatted centered output of a string. Allegro game programming library.SYNOPSIS
#include <allegro.h>
void textprintf_centre_ex(BITMAP *bmp, const FONT *f, int x, int y, int color, int bg, const char *fmt, ...);
DESCRIPTION
Like textprintf_ex(), but interprets the x coordinate as the centre rather than the left edge of the string. This function shares the text length limitation of textprintf_ex(). Example:
textprintf_centre_ex(screen, font, SCREEN_W / 2, 120,
makecol(0, 100, 243), -1,
"Your best score so far was %d!",
total_max_points);
