If you're running with Visual C++, Symantec C, or Borland's 50 * development environment on the PC, you're all set. Or if you're on the Mac 51 * with Metrowerks, Symantec or MPW with SC you're ok too. For UNIX it shouldn't 52 * matter. 53 54 * Changes by sailesh on 9/26 55 56 * There are two symbols used in the declaration of the JNI functions 57 * and native code that uses the JNI: 58 * JNICALL - specifies the calling convention 59 * JNIEXPORT - specifies export status of the function 60 * 61 * The syntax to specify calling conventions is different in Win16 and 62 * Win32 - the brains at Micro$oft at work here. JavaSoft in their 63 * infinite wisdom cares for no platform other than Win32, and so they 64 * just define these two symbols as: 65 66 #define JNIEXPORT __declspec(dllexport) 67 #define JNICALL __stdcall 68 69 * We deal with this, in the way JRI defines the JRI_PUBLIC_API, by 70 * defining a macro called JNI_PUBLIC_API. Any of our developers who 71 * wish to use code for Win16 and Win32, _must_ use JNI_PUBLIC_API to 72 * be able to export functions properly. 73 74 * Since we must also maintain compatibility with JavaSoft, we 75 * continue to define the symbol JNIEXPORT. However, use of this 76 * internally is deprecated, since it will cause a mess on Win16. 77 78 * We _do not_ need a new symbol called JNICALL. Instead we 79 * redefine JNICALL in the same way JRI_CALLBACK was defined. 80 81 ******************************************************************************/ 82 83 /* DLL Entry modifiers... */ 84 #if defined(XP_OS2) 85 # ifdef XP_OS2_VACPP 86 # define JNI_PUBLIC_API(ResultType) ResultType _System 87 # define JNI_PUBLIC_VAR(VarType) VarType 88 # define JNICALL _Optlink 89 # define JNIEXPORT 90 # else 91 # define JNI_PUBLIC_API(ResultType) ResultType 92 # define JNI_PUBLIC_VAR(VarType) VarType 93 # define JNICALL 94 # define JNIEXPORT 95 # endif 96 /* Win32 */ 97 #elif defined(XP_WIN) || defined(_WINDOWS) || defined(WIN32) || defined(_WIN32) 98 # include <windows.h> 99 # if defined(_MSC_VER) || defined(__GNUC__) 100 # if defined(WIN32) || defined(_WIN32) 101 # define JNI_PUBLIC_API(ResultType) _declspec(dllexport) ResultType __stdcall 102 # define JNI_PUBLIC_VAR(VarType) VarType 103 # define JNI_NATIVE_STUB(ResultType) _declspec(dllexport) ResultType 104 # define JNICALL __stdcall 105 # else /* !_WIN32 */ 106 # if defined(_WINDLL) 107 # define JNI_PUBLIC_API(ResultType) ResultType __cdecl __export __loadds 108 # define JNI_PUBLIC_VAR(VarType) VarType 109 # define JNI_NATIVE_STUB(ResultType) ResultType __cdecl __loadds 110 # define JNICALL __loadds 111 # else /* !WINDLL */ 112 # define JNI_PUBLIC_API(ResultType) ResultType __cdecl __export 113 # define JNI_PUBLIC_VAR(VarType) VarType 114 # define JNI_NATIVE_STUB(ResultType) ResultType __cdecl __export 115 # define JNICALL __export 116 # endif /* !WINDLL */ 117 # endif /* !_WIN32 */ 118 # elif defined(__BORLANDC__) 119 # if defined(WIN32) || defined(_WIN32) 120 # define JNI_PUBLIC_API(ResultType) __export ResultType 121 # define JNI_PUBLIC_VAR(VarType) VarType 122 # define JNI_NATIVE_STUB(ResultType) __export ResultType 123 # define JNICALL 124 # else /* !_WIN32 */ 125 # define JNI_PUBLIC_API(ResultType) ResultType _cdecl _export _loadds 126 # define JNI_PUBLIC_VAR(VarType) VarType 127 # define JNI_NATIVE_STUB(ResultType) ResultType _cdecl _loadds 128 # define JNICALL _loadds 129 # endif 130 # else 131 # error Unsupported PC development environment. 132 # endif 133 # ifndef IS_LITTLE_ENDIAN 134 # define IS_LITTLE_ENDIAN 135 # endif 136 /* This is the stuff inherited from JavaSoft .. */ 137 # define JNIEXPORT __declspec(dllexport) 138 139 140 /* Mac */ 141 #elif macintosh || Macintosh || THINK_C 142 # if defined(__MWERKS__) /* Metrowerks */ 143 # if !__option(enumsalwaysint) 144 # error You need to define 'Enums Always Int' for your project. 145 # endif 146 # if defined(TARGET_CPU_68K) && !TARGET_RT_MAC_CFM 147 # if !__option(fourbyteints) 148 # error You need to define 'Struct Alignment: 68k' for your project. 149 # endif 150 # endif /* !GENERATINGCFM */ 151 # define JNI_PUBLIC_API(ResultType) __declspec(export) ResultType 152 # define JNI_PUBLIC_VAR(VarType) JNI_PUBLIC_API(VarType) 153 # define JNI_NATIVE_STUB(ResultType) JNI_PUBLIC_API(ResultType) 154 # elif defined(__SC__) /* Symantec */ 155 # error What are the Symantec defines?
