21 * This file is used to define the FreeType module error codes.
23 * If the macro `FT_CONFIG_OPTION_USE_MODULE_ERRORS` in `ftoption.h` is
24 * set, the lower byte of an error value identifies the error code as
25 * usual. In addition, the higher byte identifies the module. For
26 * example, the error `FT_Err_Invalid_File_Format` has value 0x0003, the
27 * error `TT_Err_Invalid_File_Format` has value 0x1303, the error
28 * `T1_Err_Invalid_File_Format` has value 0x1403, etc.
30 * Note that `FT_Err_Ok`, `TT_Err_Ok`, etc. are always equal to zero,
31 * including the high byte.
33 * If `FT_CONFIG_OPTION_USE_MODULE_ERRORS` isn't set, the higher byte of an
34 * error value is set to zero.
36 * To hide the various `XXX_Err_` prefixes in the source code, FreeType
37 * provides some macros in `fttypes.h`.
41 * Add current error module prefix (as defined with the `FT_ERR_PREFIX`
42 * macro) to `err`. For example, in the BDF module the line
45 * error = FT_ERR( Invalid_Outline );
51 * error = BDF_Err_Invalid_Outline;
54 * For simplicity, you can always use `FT_Err_Ok` directly instead of
57 * FT_ERR_EQ( errcode, err )
58 * FT_ERR_NEQ( errcode, err )
60 * Compare error code `errcode` with the error `err` for equality and
61 * inequality, respectively. Example:
64 * if ( FT_ERR_EQ( error, Invalid_Outline ) )
68 * Using this macro you don't have to think about error prefixes. Of
69 * course, if module errors are not active, the above example is the
73 * if ( error == FT_Err_Invalid_Outline )
77 * FT_ERROR_BASE( errcode )
78 * FT_ERROR_MODULE( errcode )
80 * Get base error and module error code, respectively.
82 * It can also be used to create a module error message table easily with
87 * #define FT_MODERRDEF( e, v, s ) { FT_Mod_Err_ ## e, s },
88 * #define FT_MODERR_START_LIST {
89 * #define FT_MODERR_END_LIST { 0, 0 } };
94 * const char* mod_err_msg
97 * #include <freetype/ftmoderr.h>
