NAME
ggiDrawBox, ggiPutBox, ggiGetBox - Draw, put, and get a rectangle from
a visual
SYNOPSIS
#include <ggi/ggi.h>
int ggiDrawBox(ggi_visual_t vis, int x, int y, int w, int h);
int ggiPutBox(ggi_visual_t vis, int x, int y, int w, int h, const void *buf);
int ggiGetBox(ggi_visual_t vis, int x, int y, int w, int h, void *buf);
DESCRIPTION
Draw, put, or get a rectangle at (x, y), extending w pixels in the
positive x direction and h pixels in the positive y direction.
The buf parameter in Get/Put functions points to a buffer from which
the pixels will be read, or to which they will be written (it must be
correctly allocated), respectively. See ggiPackColors(3) and
ggiUnmapPixel(3) functions for details on how to deal with pixels.
RETURN VALUE
All three functions return 0 to indicate success.
