_putpixel(3)                    Allegro manual                    _putpixel(3)

NAME
       _putpixel, _putpixel15, _putpixel16, _putpixel24, _putpixel32 - Faster
       specific version of putpixel(). Allegro game programming library.

SYNOPSIS
       #include <allegro.h>

       void _putpixel(BITMAP *bmp, int x, int y, int color);

       void _putpixel15(BITMAP *bmp, int x, int y, int color);

       void _putpixel16(BITMAP *bmp, int x, int y, int color);

       void _putpixel24(BITMAP *bmp, int x, int y, int color);

       void _putpixel32(BITMAP *bmp, int x, int y, int color);

DESCRIPTION
       Like the regular putpixel(), but much faster because they are
       implemented as an inline assembler functions for specific color depths.
       These won't work in mode-X graphics modes, don't perform any clipping
       (they will crash if you try to draw outside the bitmap!), and ignore
       the drawing mode.
