[gst-devel] Question on gst_bus_add/remove_signal_watch functions

Hello everyone. I'm involved in gstreamermm with other developers in
order to provide C++ bindings for gstreamer. We're moving along quite
nicely so far, but some of us will most likely ask a few questions here
every so often (I hope this is fine :-)). One such question is related
to the gst_bus_add/remove_signal_watch[_full] functions (which I'm
presently working on right now). As I understand the docs,
gst_add_signal_watch[_full] can be called several times, but
remove_signal_watch must be called the same number of times to remove
My question is: does the message signal get transmitted as many times
as gst_bus_add_signal_watch() has been called or just once regardless?
If so, why allow several calls to gst_bus_add_signal_watch(). Also, am
I correct in assuming that the GstBus is not destroyed unless
gst_bus_remove_signal_watch() is called the same number of times that
gst_bus_add_signal_watch[_full]() has been called?
I appreciate answers as this is relevant to the C++ "wrapping" process
that we are using for the C++ bindings. Thanks.
