Way to show programs receiving dbus-signal ?
Ad
Hi dbus maillist friends:  _place_holder; _place_holder; _place_holder; _place_holder;&n bsp_place_holder;  _place_holder; I'm searching a way to get which programs or processes have interested in specific dbus-signal, given by name,interface of dbus-signal. It's helpful for seeing system's status & debugging. Does someone kindly tell me whether there is a simple way or deep into source code of dbus? Thanks. Cheers Liang.

Second, I'm sorry but there's no way to retrieve the information about which
connections have demonstrated interest in a particular signal.
If you really wish to get this information, you can modify the daemon so that
you can retrieve the list of match rules and the connections they apply to.
Then use the rules to determine which connections are interested in those
signals. Note that rules like "type='signal'" will match for any and all
signals.
