NAME

       vga_setreadpage - set the 64K SVGA page number

SYNOPSIS

       #include <vga.h>

       void vga_setreadpage(int page);

DESCRIPTION

       Usually  SVGA  cards have more than the 64K memory which suffice for an
       ordinary VGA.  However, the memory window mapped at  vga_getgraphmem(3)
       is  only  64K  bytes  large.  vga_setreadpage() selects the page-th 64K
       memory chunk to be visible for reads at position vga_getgraphmem(3).

       vga_setwritepage(3) allows a different 64K memory chunk to be  modified
       by  writes  to  this  memory  window. This is a very useful feature for
       screen to screen pixmap copies. However, not all cards support this  in
       all graphics mode. Check vga_modeinfo(3) for availability. Esp. as this
       feature can also not be used when in background mode.

       Of  course,  this  function  must   be   used   in   conjunction   with
       vga_setwritepage(3)   but   may   not   be  used  in  conjunction  with
       vga_setpage(3).
