_putpixel(3alleg4)                        Allegro manual                       _putpixel(3alleg4)

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.
