<para>
When writing a <application>GStreamer</application> application, you can
simply include gst/gst.h to get access to the library functions.
</para>
<para>
Before the <application>GStreamer</application> libraries can be used
gst_init () has to be performed from the main app. this call will perform
first initialisation and will parse the GStreamer specific command line
options.
</para>
<para>
A typical program would start like this:
</para>
<programlisting>
#include &lt;gst/gst.h&gt;
...
int
main (int argc, char *argv[])
{
...
gst_init (&amp;argc, &amp;argv);
...
}
</programlisting>
<para>
It is also possible to call the gst_init method with two NULL argumants.
</para>
<para>
Use the GST_VERSION_MAJOR, GST_VERSION_MINOR and GST_VERSION_MICRO macros to
get the <application>GStreamer</application> version you are building against.
