28 * @short_description: GStreamer version macros.
30 * Use the GST_VERSION_* macros e.g. when defining own plugins. The GStreamer
31 * runtime checks if these plugin and core version match and refuses to use a
32 * plugin compiled against a different version of GStreamer.
33 * You can also use the macros to keep the GStreamer version information in
36 * Use the gst_version() function if you want to know which version of
37 * GStreamer you are currently linked against.
39 * The version macros get defined by including "gst/gst.h".
47 * The major version of GStreamer at compile time:
49 #define GST_VERSION_MAJOR (@GST_VERSION_MAJOR@)
53 * The minor version of GStreamer at compile time:
55 #define GST_VERSION_MINOR (@GST_VERSION_MINOR@)
59 * The micro version of GStreamer at compile time:
61 #define GST_VERSION_MICRO (@GST_VERSION_MICRO@)
65 * The nano version of GStreamer at compile time:
66 * Actual releases have 0, GIT versions have 1, prerelease versions have 2-...
68 #define GST_VERSION_NANO (@GST_VERSION_NANO@)
72 * @major: a number indicating the major version
73 * @minor: a number indicating the minor version
74 * @micro: a number indicating the micro version
76 * Check whether a GStreamer version equal to or greater than
77 * major.minor.micro is present.
