<a name="cogl-2.0-experimental-Versioning-utility-macros.description"></a><h2>Description</h2>
<p>Cogl offers a set of macros for checking the version of the library
at compile time.</p>
<p>Cogl adds version information to both API deprecations and additions;
by definining the macros <code class="literal">COGL_VERSION_MIN_REQUIRED</code> and
<code class="literal">COGL_VERSION_MAX_ALLOWED</code>, you can specify the range of Cogl versions
whose API you want to use. Functions that were deprecated before, or
introduced after, this range will trigger compiler warnings. For instance,
if we define the following symbols:</p>
<div class="informalexample"><pre class="programlisting">
  COGL_VERSION_MIN_REQUIRED = COGL_VERSION_1_6
  COGL_VERSION_MAX_ALLOWED  = COGL_VERSION_1_8
</pre></div>
<p></p>
<p>and we have the following functions annotated in the Cogl headers:</p>
<div class="informalexample"><pre class="programlisting">
  COGL_DEPRECATED_IN_1_4 void cogl_function_A (void);
  COGL_DEPRECATED_IN_1_6 void cogl_function_B (void);
  COGL_AVAILABLE_IN_1_8 void cogl_function_C (void);
  COGL_AVAILABLE_IN_1_10 void cogl_function_D (void);
</pre></div>
<p></p>
<p>then any application code using the functions above will get the output:</p>
<div class="informalexample"><pre class="programlisting">
  cogl_function_A: deprecation warning
  cogl_function_B: no warning
  cogl_function_C: no warning
  cogl_function_D: symbol not available warning
</pre></div>
<p></p>
<p>It is possible to disable the compiler warnings by defining the macro
<code class="literal">COGL_DISABLE_DEPRECATION_WARNINGS</code> before including the cogl.h
header.</p>

<a name="COGL-VERSION-ENCODE:CAPS"></a><h3>COGL_VERSION_ENCODE()</h3>
<pre class="programlisting">#define             COGL_VERSION_ENCODE(major, minor, micro)</pre>
<p>Encodes a 3 part version number into a single integer. This can be
used to compare the Cogl version. For example if there is a known
bug in Cogl versions between 1.3.2 and 1.3.4 you could use the
following code to provide a workaround:</p>
<div class="informalexample"><pre class="programlisting">
#if COGL_VERSION &gt;= COGL_VERSION_ENCODE (1, 3, 2) &amp;&amp; \
    COGL_VERSION &lt;= COGL_VERSION_ENCODE (1, 3, 4)
  /&lt;!-- --&gt;* Do the workaround *&lt;!-- --&gt;/

<pre class="programlisting">#define             COGL_VERSION_CHECK(major, minor, micro)</pre>
<p>A convenient macro to check whether the Cogl version being compiled
against is at least the given version number. For example if the
function cogl_pipeline_frobnicate was added in version 2.0.1 and
you want to conditionally use that function when it is available,
you could write the following:</p>
<div class="informalexample"><pre class="programlisting">
#if COGL_VERSION_CHECK (2, 0, 1)
cogl_pipeline_frobnicate (pipeline);
#else
/&lt;!-- --&gt;* Frobnication is not supported. Use a red color instead *&lt;!-- --&gt;/
