Dear Lionel/All,
Thanks Lionel for your response.
Currently we are calling Lock() after CreateSurface().
But we don't get any error on Lock() after complete usage of video memory.
We tried to call the function,
surface->Clear(surface, 0 , 0, 0, 255);
after calling CreateSurface(). But in that case, system hang on Clear()
function.
The surface format we used is DSPF_UYVY.
Is there any issue for Clear() on YUV surface since there is no alpha value.
Can any one please tell what should we do next??
Thanks a lot!!!
Regards,
Lindo.

Ok, now I remember that in directfb 1.4, buffers are allocated at the
last moment. So you need to make at least one operation on your buffers
to be sure they have been allocated.
For example you can that :
surface = SuperSurface->CreateSurface(...)
ret = surface->Clear(...)
/* check if ret == DFB_NOVIDEOMEMORY */
or
surface = SuperSurface->CreateSurface(...)
ret = surface->Lock(...)
/* check if ret == DFB_NOVIDEOMEMORY */
surface->Unlock(...)

Dear Lionel/All,
Our configuration is "system=fbdev" and gfxdriver is a proprietary
one.

Dear all,
Our question is related to DirectFB-1.4.2.
We are working in an embedded platform.
We are creating IDirectFBSurface using CreateSurface() API. In the test
application we are creating a lot of surfaces. We are using the
following settings in DFBSurfaceDescription,
....
surfaceDesc.flags = DSDESC_CAPS | ....;
surfaceDesc.caps = DSCAPS_VIDEOONLY;
....
But even after complete usage of video memory, the CreateSurface() is
not returning any error. We expect an DFBResult DFB_NOVIDEOMEMORY in
this scenario. We get this DFBResult when we test with DirectFB-1.0.
Is this is a bug in DirectFB-1.4?
If yes, can any one please tell, what should we do to solve this or
where should we look?
If this is not a bug, what should we do to know video memory underflow
happened?
What system/gfxdriver are you using ?
