NAME

       ggiDrawHLine,   ggiPutHLine,   ggiGetHLine  -  Draw,  put,  and  get  a
       horizontal line from a visual

SYNOPSIS

       #include <ggi/ggi.h>

       int ggiDrawHLine(ggi_visual_t vis, int x, int y, int w);

       int ggiPutHLine(ggi_visual_t vis, int x, int y, int w, const void *buf);

       int ggiGetHLine(ggi_visual_t vis, int x, int y, int w, void *buf);

DESCRIPTION

       Draw, put, or get a horizontal line from (x, y), extending w pixels  in
       the positive x direction (normally right).  The height is one pixel.

       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.
