Dear Shivakumar,
Thanks for your reply.
Sorry for posting the same mail again in user's list. It's a mistake
from me.
Dear Shivakumar/all,
I am expecting more clarifications in Question number 4.( What is mean
by smooth running. Is any crash/undefined behavious occur?)
Can some one give me some explanation for Question number 5.
Thanks & Regards,
Lindo Lonappan.

Dear All,
I am using DirectFB-1.0.0.
>From the code and Google, we found that IDirectFB interface
is a singleton one.
So the subsequent call to the DirectFBInit() will simply
return without changing any configuration
and DirectFBCreate() call will return a reference to first
IDirectFB handler.
Our questions are,
1. We are configured, DirectFB as single core mode(ie without
any fusion module).
Is this is sufficient even if there is multiple
DirectFBInit/DirectFBCreate call from the same applications?
You can call multiple times .But it will give you same instance.It
has no effect.
2. Can we control the z-order of windows in this case also?
(The two windows are created from two different references)
Yes you can.
3. If above is possible can any one lead me to the APIs for that?
(Both at the time of Creating new window and at run time)
There are two ways:-
1. Create window with different layer and SetLevel for that
layer(according to your requirement)
2.You can use these api for specific window:- (If you want it
from window operation)
SetStackingClass,Raise,RaiseToTop,Lower etc. go through link:-
http://directfb.org/docs/DirectFB_Reference_1_4/IDirectFBWindow.html
4. Is fusion always necessary if there is multilple
applications over DFB?
(I read, it is required for IPCs. Can anyone explain a
little more details)
No (But necessary for smoother running of applications).
5. Inside fusion module, there is a mmap() which using a flag
MAP_FIXED.
In our system the addresses it tries to map is already used
by some other one and we are not able to free that.
So is there any way to change this fixed address need??
Thanks a lot for your valuable time.
