Hi guys,
i'm trying to build two processes that use same reference of DFB.
my first step was compile linux-fusion (fusion.ko) and dfb with
--enable-multi. after this i create 2 executables. The code fragments of
processes will be showed below:
-- first process --
DFBSurfaceDescription dsc;
DirectFBInit (&argc, &argv);
DirectFBCreate (&dfb);
dfb->SetCooperativeLevel (dfb, DFSCL_FULLSCREEN);
dfb->GetDisplayLayer(dfb, DLID_PRIMARY, &layer);
dsc.flags = DSDESC_CAPS;
dsc.caps = DSCAPS_PRIMARY | DSCAPS_FLIPPING;
dfb->CreateSurface( dfb, &dsc, &primary );
primary->GetSize (primary, &screen_width, &screen_height);
-- second process (same code)--
DFBSurfaceDescription dsc;
DirectFBInit (&argc, &argv);
DirectFBCreate (&dfb);
dfb->SetCooperativeLevel (dfb, DFSCL_FULLSCREEN);
dfb->GetDisplayLayer(dfb, DLID_PRIMARY, &layer);
dsc.flags = DSDESC_CAPS;
dsc.caps = DSCAPS_PRIMARY | DSCAPS_FLIPPING;
dfb->CreateSurface( dfb, &dsc, &primary );
primary->GetSize (primary, &screen_width, &screen_height);
so i compiled these two codes and executed them. but i think that this way
is incorrect, because to get DFB reference I used DFBInit and to get primary
surface I created it again.
Am I mistaking? or am I rigth?
best regards.
