ggiDrawVLine(3)			      GGI		       ggiDrawVLine(3)

NAME
       ggiDrawVLine,  ggiPutVLine, ggiGetVLine : Draw, put, and get a vertical
       line from a visual

SYNOPSIS
       #include <ggi/ggi.h>

       int ggiDrawVLine(ggi_visual_t vis, int x, int y, int h);

       int ggiPutVLine(ggi_visual_t vis, int x, int y, int h, const void *buf);

       int ggiGetVLine(ggi_visual_t vis, int x, int y, int h, void *buf);

DESCRIPTION
       Draw, put, or get a vertical line from (x, y), extending	 h  pixels  in
       the  positive y direction (normally down). The width of the line 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  ggiUnmap‐
       Pixel(3) functions for details on how to deal with pixels.

RETURN VALUE
       All three functions return 0 to indicate success.
