Hi,

     I am creating surface like this

g_bs = malloc(g_width * g_height * 4);
  dsc.flags = DSDESC_CAPS | DSDESC_WIDTH | DSDESC_HEIGHT |
              DSDESC_PREALLOCATED | DSDESC_PIXELFORMAT;
  dsc.caps = DSCAPS_SYSTEMONLY;
  dsc.width = g_width;
  dsc.height = g_height;
  dsc.pixelformat = DSPF_ARGB;
  dsc.preallocated[0].data = g_bs;
  dsc.preallocated[0].pitch = g_width * 4;
g_dfb->CreateSurface(g_dfb, &dsc, &g_s)

if u use Blit function then its giving following errors:
:DirectFB/Genefx: Could not lock source!
    --> Not supported!
:DirectFB/Genefx: Could not lock source!
    --> Not supported!
can one help me to eliminate this error.

Thanks
Mohan.
