30 * @short_description: GStreamer version macros.
31 *
32 * Use the GST_VERSION_* macros e.g. when defining own plugins. The GStreamer
33 * runtime checks if these plugin and core version match and refuses to use a
34 * plugin compiled against a different version of GStreamer.
35 * You can also use the macros to keep the GStreamer version information in
36 * your application.
37 *
38 * Use the gst_version() function if you want to know which version of
39 * GStreamer you are currently linked against.
40 *
41 * The version macros get defined by including "gst/gst.h".
