How to use dbus as the IPC sync method in different IPC namespace

[yinxb]

Hi Experts

   These days I encountered a problem.
   I have an App running  in its own IPC name space for isolation purpose,
   and now I need to do IPC sync with App(which is known as UX)
running in another IPC namespace  for UI display sync.

   Does dbus has the capability to do so?
   Semaphore failed in this case.

   Any reply will be appreciate.
   Thanks in advance!
