⇱ man textprintf_centre_ex (3): Formatted centered output of a string. Allegro game programming library.

textprintf_centre_ex(3) 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);
