-Poll the bus for messages. Will block while waiting for messages to come.
-You can specify a maximum time to poll with the @timeout parameter. If
-All messages not in @events will be popped off the bus and will be ignored.
-Because poll is implemented using the "message" signal enabled by
-gst_bus_add_signal_watch(), calling gst_bus_poll() will cause the "message"
-signal to be emitted for every message that poll sees. Thus a "message"
-signal handler will see the same messages that this function sees -- neither
-will steal messages from the other.
-This function will run a main loop from the default main context when

-You should never use this function, since it is pure evil. This is

-other non-trivial application that uses the GLib main loop. As this function
-runs a GLib main loop, any callback attached to the default GLib main
-context may be invoked. This could be timeouts, GUI events, I/O events etc.;
-even if gst_bus_poll() is called with a 0 timeout. Any of these callbacks
-may do things you do not expect, e.g. destroy the main application window or
-some other resource; change other application state; display a dialog and
-run another main loop until the user clicks it away. In short, using this
-function may add a lot of complexity to your code through unexpected
-re-entrancy and unexpected changes to your application's state.
-For 0 timeouts use gst_bus_pop_filtered() instead of this function; for
-other short timeouts use gst_bus_timed_pop_filtered(); everything else is
-better handled by setting up an asynchronous bus watch and doing things
-from there.

+Poll the bus for messages. Will block while waiting for messages to come.
+You can specify a maximum time to poll with the @timeout parameter. If
+All messages not in @events will be popped off the bus and will be ignored.
+Because poll is implemented using the "message" signal enabled by
+gst_bus_add_signal_watch(), calling gst_bus_poll() will cause the "message"
+signal to be emitted for every message that poll sees. Thus a "message"
+signal handler will see the same messages that this function sees -- neither
+will steal messages from the other.
+This function will run a main loop from the default main context when
+polling.
+You should never use this function, since it is pure evil. This is
+especially true for GUI applications based on Gtk+ or Qt, but also for any
+other non-trivial application that uses the GLib main loop. As this function
+runs a GLib main loop, any callback attached to the default GLib main
+context may be invoked. This could be timeouts, GUI events, I/O events etc.;
+even if gst_bus_poll() is called with a 0 timeout. Any of these callbacks
+may do things you do not expect, e.g. destroy the main application window or
+some other resource; change other application state; display a dialog and
+run another main loop until the user clicks it away. In short, using this
+function may add a lot of complexity to your code through unexpected
+re-entrancy and unexpected changes to your application's state.
+For 0 timeouts use gst_bus_pop_filtered() instead of this function; for
+other short timeouts use gst_bus_timed_pop_filtered(); everything else is
+better handled by setting up an asynchronous bus watch and doing things
+from there.
