As per my understanding, dbus re-use the share connection. So if you do dbus_bus_get(). Then it checks for any existing free connection with the given bus, if it available then it allocate it for application, if no free connection available then it create a new connection and keep its record to reuse it. Thats why we can't close the shared connection, if we try to do so , dbus gives a runtime error. But a private connection is dedicated to calling application and should be close by application at the end. Not sure but in my understanding this rule is followed more strictly in the case of system bus because the shared connections are system wide and can be shared between different sessions. While in the case of session bus the shared connections are limited to only particular session. -Br Naveen <div class="gmail_quote">On Jan 8, 2008 3:55 PM, Ge@@ru <<a href="mailto:geaaru@gmail.com">geaaru@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> On dbus session (share connection) works fine. Only on system session i have this problem. So, why i can't close this shared connection?
