This is the interface age passed to <span class="application">libtool</span>. If 
<span class="application">libtool</span> means nothing to you, don't worry

Checks that the GTK+ library in use is compatible with the
given version. Generally you would pass in the constants
<a class="link" href="gtk-Feature-Test-Macros.html#GTK-MAJOR-VERSION:CAPS"><span class="type">GTK_MAJOR_VERSION</span></a>, <a class="link" href="gtk-Feature-Test-Macros.html#GTK-MINOR-VERSION:CAPS"><span class="type">GTK_MINOR_VERSION</span></a>, <a class="link" href="gtk-Feature-Test-Macros.html#GTK-MICRO-VERSION:CAPS"><span class="type">GTK_MICRO_VERSION</span></a>
as the three arguments to this function; that produces
a check that the library in use is compatible with
the version of GTK+ the application or module was compiled
against.
</p>
<p>
Compatibility is defined by two things: first the version
of the running library is newer than the version
<em class="parameter"><code>required_major.required_minor</code></em>.<em class="parameter"><code>required_micro</code></em>. Second
the running library must be binary compatible with the
version <em class="parameter"><code>required_major.required_minor</code></em>.<em class="parameter"><code>required_micro</code></em>
(same major version.)
</p>
<p>
This function is primarily for GTK+ modules; the module
can call this function to check that it wasn't loaded
into an incompatible version of GTK+. However, such a
a check isn't completely reliable, since the module may be
linked against an old version of GTK+ and calling the
old version of <a class="link" href="gtk-Feature-Test-Macros.html#gtk-check-version"><code class="function">gtk_check_version()</code></a>, but still get loaded
into an application using a newer version of GTK+.</p>
