<p>The list below is taken verbatim from the file <code>fterrdef.h</code> (loaded automatically by including <code>FT_FREETYPE_H</code>). The first argument of the <code>FT_ERROR_DEF_</code> macro is the error label; by default, the prefix <code>FT_Err_</code> gets added so that you get error names like <code>FT_Err_Cannot_Open_Resource</code>. 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 <strong>only</strong> use error names and <strong>never</strong> its numeric values! The latter might (and actually do) change in forthcoming FreeType versions.</p>
<p>Macro <code>FT_NOERRORDEF_</code> defines <code>FT_Err_Ok</code>, which is always zero. See the ‘Error Enumerations’ subsection how to automatically generate a list of error strings.</p>
