FreeType-2.8.1 API Reference

Error Code Values

Synopsis

FT_Err_XXX

The list below is taken verbatim from the file ‘fterrdef.h’ (loaded automatically by including ‘FT_FREETYPE_H’). The first argument of the ‘FT_ERROR_DEF_’ macro is the error label; by default, the prefix ‘FT_Err_’ gets added so that you get error names like ‘FT_Err_Cannot_Open_Resource’. The second argument is the error code, and the last argument an error string, which is not used by FreeType.

Within your application you should only use error names and never its numeric values! The latter might (and actually do) change in forthcoming FreeType versions.

Macro ‘FT_NOERRORDEF_’ defines ‘FT_Err_Ok’, which is always zero. See the ‘Error Enumerations’ subsection how to automatically generate a list of error strings.
