vga_copytoplanar256

[caustik]

Why doesnt this work..? I desperately need a linear blit to a modeX[320x240x256]...   
If you have ANY example source that uses vga_copytoplanar256, it would be greatly 
appreciated..thanks

#include <malloc.h>
#include <stdio.h>
#include <vga.h>

unsigned char *pixels = (unsigned char *)malloc(320*240);

int main()
{
   vga_init();

   vga_setmode(G320x240x256);
   vga_setmodeX();

   for(int ind=0;ind<256;ind++)
        vga_setpalette(ind,ind,0,0);

   for(int v=0;v<320*240;v++)
        pixels[v]=0x88;

   vga_copytoplanar256(pixels,320,0,320,320,40);

   vga_setpage(0);

   vga_getch();

   vga_setmode(TEXT);

   exit(0);
}
