/**************************************************************************
|
|
*
|
|
* This file is used to define the FreeType module error codes.
|
|
*
|
|
* If the macro `FT_CONFIG_OPTION_USE_MODULE_ERRORS` in `ftoption.h` is
|
|
* set, the lower byte of an error value identifies the error code as
|
|
* usual. In addition, the higher byte identifies the module. For
|
|
* example, the error `FT_Err_Invalid_File_Format` has value 0x0003, the
|
|
* error `TT_Err_Invalid_File_Format` has value 0x1303, the error
|
|
* `T1_Err_Invalid_File_Format` has value 0x1403, etc.
|
|
*
|
|
* Note that `FT_Err_Ok`, `TT_Err_Ok`, etc. are always equal to zero,
|
|
* including the high byte.
|
|
*
|
|
* If `FT_CONFIG_OPTION_USE_MODULE_ERRORS` isn't set, the higher byte of an
|
|
* error value is set to zero.
|
|
*
|
|
* To hide the various `XXX_Err_` prefixes in the source code, FreeType
|
|
* provides some macros in `fttypes.h`.
|
|
*
|
|
* FT_ERR( err )
|
|
*
|
|
* Add current error module prefix (as defined with the `FT_ERR_PREFIX`
|
|
* macro) to `err`. For example, in the BDF module the line
|
|
*
|
|
* ```
|
|
* error = FT_ERR( Invalid_Outline );
|
|
* ```
|
|
*
|
|
* expands to
|
|
*
|
|
* ```
|
|
* error = BDF_Err_Invalid_Outline;
|
|
* ```
|
|
*
|
|
* For simplicity, you can always use `FT_Err_Ok` directly instead of
|
|
* `FT_ERR( Ok )`.
|
|
*
|
|
* FT_ERR_EQ( errcode, err )
|
|
* FT_ERR_NEQ( errcode, err )
|
|
*
|
|
* Compare error code `errcode` with the error `err` for equality and
|
|
* inequality, respectively. Example:
|
|
*
|
|
* ```
|
|
* if ( FT_ERR_EQ( error, Invalid_Outline ) )
|
|
* ...
|
|
* ```
|
|
*
|
|
* Using this macro you don't have to think about error prefixes. Of
|
|
* course, if module errors are not active, the above example is the
|
|
* same as
|
|
*
|
|
* ```
|
|
* if ( error == FT_Err_Invalid_Outline )
|
|
* ...
|
|
* ```
|
|
*
|
|
* FT_ERROR_BASE( errcode )
|
|
* FT_ERROR_MODULE( errcode )
|
|
*
|
|
* Get base error and module error code, respectively.
|
|
*
|
|
* It can also be used to create a module error message table easily with
|
|
* something like
|
|
*
|
|
* ```
|
|
* #undef FTMODERR_H_
|
|
* #define FT_MODERRDEF( e, v, s ) { FT_Mod_Err_ ## e, s },
|
|
* #define FT_MODERR_START_LIST {
|
|
* #define FT_MODERR_END_LIST { 0, 0 } };
|
|
*
|
|
* const struct
|
|
* {
|
|
* int mod_err_offset;
|
|
* const char* mod_err_msg
|
|
* } ft_mod_errors[] =
|
|
*
|
|
* #include FT_MODULE_ERRORS_H
|
|
* ```
|
|
*
