| <p> |
| Use the GST_VERSION_* macros e.g. when defining own plugins. The GStreamer |
| runtime checks if these plugin and core version match and refuses to use a |
| plugin compiled against a different version of GStreamer. |
| You can also use the macros to keep the GStreamer version information in |
| your application. |
| </p> |
| <p> |
| Use the <a class="link" href="gstreamer-Gst.html#gst-version" title="gst_version ()"><code class="function">gst_version()</code></a> function if you want to know which version of |
| GStreamer you are currently linked against. |
| </p> |
| <p> |
| The version macros get defined by including "gst/gst.h". |
