7       memory

SYNOPSIS

10       #include <vga.h>
11
12       void vga_copytoplanar16(unsigned char *virtual, int pitch, int voffset,
13       int vpitch, int w, int h);

DESCRIPTION

17       Similar  to  vga_copytoplanar256(3),  but  for 16 color modes (not well
18       tested). Assumes pixels stored in consecutive bytes ranging from  0  to
19       15 in the virtual screen.
20
21       Copies  part of a linear virtual screen in system memory at *virtual to
22       VGA 16 mode video memory.  pitch is the logical width  of  the  virtual
23       screen  (in  pixels (which are one byte large)), voffset is the address
24       offset into video memory, vpitch is the logical scanline width  of  the
25       screen.   (w,  h) is the size of the area to copy in pixels (width must
26       be multiple of 4).
