<p>Return the version of the FreeType library being used. This is useful when dynamically linking to the library, since one cannot use the macros <code><a href="ft2-version.html#freetype_xxx">FREETYPE_MAJOR</a></code>, <code><a href="ft2-version.html#freetype_xxx">FREETYPE_MINOR</a></code>, and <code><a href="ft2-version.html#freetype_xxx">FREETYPE_PATCH</a></code>.</p>

<h4>note</h4>

<p>The reason why this function takes a <code>library</code> argument is because certain programs implement library initialization in a custom way that doesn't use <code><a href="ft2-base_interface.html#ft_init_freetype">FT_Init_FreeType</a></code>.</p>
<p>In such cases, the library version might not be available before the library object has been created.</p>
