<p>The list below is taken verbatim from the file &lsquo;fterrdef.h&rsquo; (loaded automatically by including &lsquo;FT_FREETYPE_H&rsquo;). The first argument of the &lsquo;FT_ERROR_DEF_&rsquo; macro is the error label; by default, the prefix &lsquo;FT_Err_&rsquo; gets added so that you get error names like &lsquo;FT_Err_Cannot_Open_Resource&rsquo;. The second argument is the error code, and the last argument an error string, which is not used by FreeType.</p>
<p>Within your application you should <b>only</b> use error names and <b>never</b> its numeric values! The latter might (and actually do) change in forthcoming FreeType versions.</p>
<p>Macro &lsquo;FT_NOERRORDEF_&rsquo; defines &lsquo;FT_Err_Ok&rsquo;, which is always zero. See the &lsquo;Error Enumerations&rsquo; subsection how to automatically generate a list of error strings.</p>
