<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 <a href="ft2-version.html#FREETYPE_XXX">FREETYPE_MAJOR</a>, <a href="ft2-version.html#FREETYPE_XXX">FREETYPE_MINOR</a>, and <a href="ft2-version.html#FREETYPE_XXX">FREETYPE_PATCH</a>.</p>

<h4>note</h4>
<p>The reason why this function takes a ‘library’ argument is because certain programs implement library initialization in a custom way that doesn't use <a href="ft2-base_interface.html#FT_Init_FreeType">FT_Init_FreeType</a>.</p>
<p>In such cases, the library version might not be available before the library object has been created.</p>
