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) 2002-2003 Fred L.
