Make the GST_POLL debug category symbol private to libgstreamer, as there should be no external users of it.

/**
|
|
* SECTION:gstinfo
|
|
* @short_description: Debugging and logging facilities
|
|
* @see_also: #GstConfig, #Gst for command line parameters
|
|
* and environment variables that affect the debugging output.
|
|
*
|
|
* GStreamer's debugging subsystem is an easy way to get information about what
|
|
* the application is doing. It is not meant for programming errors. Use GLib
|
|
* methods (g_warning and friends) for that.
|
|
*
|
|
* The debugging subsystem works only after GStreamer has been initialized
|
|
* - for example by calling gst_init().
|
|
*
|
|
* The debugging subsystem is used to log informational messages while the
|
|
* application runs. Each messages has some properties attached to it. Among
|
|
* these properties are the debugging category, the severity (called "level"
|
|
* here) and an optional #GObject it belongs to. Each of these messages is sent
|
|
* to all registered debugging handlers, which then handle the messages.
|
|
* GStreamer attaches a default handler on startup, which outputs requested
|
|
* messages to stderr.
|
|
*
|
|
* Messages are output by using shortcut macros like #GST_DEBUG,
|
|
* #GST_CAT_ERROR_OBJECT or similar. These all expand to calling gst_debug_log()
|
|
* with the right parameters.
|
|
* The only thing a developer will probably want to do is define his own
|
|
* categories. This is easily done with 3 lines. At the top of your code,
|
|
* declare
|
|
* the variables and set the default category.
|
|
* <informalexample>
|
|
* <programlisting>
|
|
* GST_DEBUG_CATEGORY_STATIC (my_category); // define category (statically)
|
|
* &hash;define GST_CAT_DEFAULT my_category // set as default
|
|
* </programlisting>
|
|
* </informalexample>
|
|
* After that you only need to initialize the category.
|
|
* <informalexample>
|
|
* <programlisting>
|
|
* GST_DEBUG_CATEGORY_INIT (my_category, "my category",
|
|
* 0, "This is my very own");
|
|
* </programlisting>
|
|
* </informalexample>
|
|
* Initialization must be done before the category is used first.
|
|
* Plugins do this
|
|
* in their plugin_init function, libraries and applications should do that
|
|
* during their initialization.
|
|
*
|
|
* The whole debugging subsystem can be disabled at build time with passing the
|
|
* --disable-gst-debug switch to configure. If this is done, every function,
|
|
* macro and even structs described in this file evaluate to default values or
|
|
* nothing at all.
|
|
* So don't take addresses of these functions or use other tricks.
|
|
* If you must do that for some reason, there is still an option.
|
|
* If the debugging
|
|
* subsystem was compiled out, #GST_DISABLE_GST_DEBUG is defined in
|
|
* <gst/gst.h>,
|
|
* so you can check that before doing your trick.
|
|
* Disabling the debugging subsystem will give you a slight (read: unnoticeable)
|
|
* speed increase and will reduce the size of your compiled code. The GStreamer
|
|
* library itself becomes around 10% smaller.
|
|
*
|
|
* Please note that there are naming conventions for the names of debugging
|
|
* categories. These are explained at GST_DEBUG_CATEGORY_INIT().
