Retained the license documents and updated the header files. --- include/freetype/ftmoderr.h | 203 ++++++++++++++++++++++++++++---------------- 1 file changed, 129 insertions(+), 74 deletions(-) (limited to 'include/freetype/ftmoderr.h') diff --git a/include/freetype/ftmoderr.h b/include/freetype/ftmoderr.h index 59e15c10..6722fbf8 100644 --- a/include/freetype/ftmoderr.h +++ b/include/freetype/ftmoderr.h @@ -1,61 +1,107 @@ -/***************************************************************************/ -/* */ -/* ftmoderr.h */ -/* */ -/* FreeType module error offsets (specification). */ -/* */ -/* Copyright 2001, 2002 by */ -/* David Turner, Robert Wilhelm, and Werner Lemberg. */ -/* */ -/* This file is part of the FreeType project, and may only be used, */ -/* modified, and distributed under the terms of the FreeType project */ -/* license, LICENSE.TXT.

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`.
