1 /* internal.h 2 3 Internal definitions used by Expat. This is not needed to compile 4 client code. 5 6 The following calling convention macros are defined for frequently 7 called functions: 8 9 FASTCALL - Used for those internal functions that have a simple 10 body and a low number of arguments and local variables. 11 12 PTRCALL - Used for functions called though function pointers. 13 14 PTRFASTCALL - Like PTRCALL, but for low number of arguments. 15 16 inline - Used for selected internal functions for which inlining 17 may improve performance on some platforms. 18 19 Note: Use of these macros is based on judgement, not hard rules, 20 and therefore subject to change. 21 __ __ _ 22 ___\ \/ /_ __ __ _| |_ 23 / _ \\ /| '_ \ / _` | __| 24 | __// \| |_) | (_| | |_ 25 \___/_/\_\ .__/ \__,_|\__| 26 |_| XML parser 27 28 Copyright (c) 1997-2000 Thai Open Source Software Center Ltd 29 Copyright (c) 2000-2017 Expat development team 30 Licensed under the MIT license: 31 32 Permission is hereby granted, free of charge, to any person obtaining 33 a copy of this software and associated documentation files (the 34 "Software"), to deal in the Software without restriction, including 35 without limitation the rights to use, copy, modify, merge, publish, 36 distribute, sublicense, and/or sell copies of the Software, and to permit 37 persons to whom the Software is furnished to do so, subject to the 38 following conditions: 39 40 The above copyright notice and this permission notice shall be included 41 in all copies or substantial portions of the Software. 42 43 THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, 44 EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF 45 MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
