/* 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 } }; */
