The only one which is 34 expected to be directly useful in client code is XMLCALL. 35 36 Note that on at least some Unix versions, the Expat library must be 37 compiled with the cdecl calling convention as the default since 38 system headers may assume the cdecl convention. 39 */ 40 #ifndef XMLCALL 41 #if defined(_MSC_VER) 42 #define XMLCALL __cdecl 43 #elif defined(__GNUC__) && defined(__i386) && !defined(__INTEL_COMPILER) 44 #define XMLCALL __attribute__((cdecl)) 45 #else 46 /* For any platform which uses this definition and supports more than 47 one calling convention, we need to extend this definition to 48 declare the convention used on that platform, if it's possible to 49 do so. 50 51 If this is the case for your platform, please file a bug report 52 with information on how to identify your platform via the C 53 pre-processor and how to specify the same calling convention as the 54 platform's malloc() implementation. 55 */ 56 #define XMLCALL 57 #endif 58 #endif /* not defined XMLCALL */ 59 60 61 #if !defined(XML_STATIC) && !defined(XMLIMPORT) 62 #ifndef XML_BUILDING_EXPAT 63 /* using Expat from an application */ 64 65 #ifdef XML_USE_MSC_EXTENSIONS 66 #define XMLIMPORT __declspec(dllimport) 67 #endif 68 69 #endif 70 #endif /* not defined XML_STATIC */ 71 72 73 /* If we didn't define it above, define it away: */ 74 #ifndef XMLIMPORT 75 #define XMLIMPORT 76 #endif 77 78 79 #define XMLPARSEAPI(type) XMLIMPORT type XMLCALL 80 81 #ifdef __cplusplus 82 extern "C" { 83 #endif 84 85 #ifdef XML_UNICODE_WCHAR_T 86 #define XML_UNICODE 87 #endif 88 89 #ifdef XML_UNICODE /* Information is UTF-16 encoded. */ 90 #ifdef XML_UNICODE_WCHAR_T 91 typedef wchar_t XML_Char; 92 typedef wchar_t XML_LChar; 93 #else 94 typedef unsigned short XML_Char; 95 typedef char XML_LChar; 96 #endif /* XML_UNICODE_WCHAR_T */ 97 #else /* Information is UTF-8 encoded. */ 98 typedef char XML_Char; 99 typedef char XML_LChar; 100 #endif /* XML_UNICODE */ 101 102 #ifdef XML_LARGE_SIZE /* Use large integers for file/stream positions. */ 103 #if defined(XML_USE_MSC_EXTENSIONS) && _MSC_VER < 1400 104 typedef __int64 XML_Index; 105 typedef unsigned __int64 XML_Size; 106 #else 107 typedef long long XML_Index; 108 typedef unsigned long long XML_Size; 109 #endif 110 #else 111 typedef long XML_Index; 112 typedef unsigned long XML_Size; 113 #endif /* XML_LARGE_SIZE */ 114 115 #ifdef __cplusplus 116 } 117 #endif 118 119 #endif /* not Expat_External_INCLUDED */ 120
