[vbox-dev] C binding and event queue

[Eric Ros]

Thanks Pritesh, I finally have the SDK eventing example working in OSE
(using the C binding). But I would like this example to work in VirtualBox
(not OSE),  so I have installed the version 2.2.2 and tried to execute
'tstXPCOMCCall', but I get the error " ./tstXPCOMCCall: FATAL: VBoxCGlueInit
failed: /usr/lib/virtualbox/VBoxXPCOMC.so: pfnGetFunctions(0x20000) failed
". I suppose this is an incompatibility issue between both versions of
VBox.. any ideas??
