If you're running with Visual C++, Symantec C, or Borland's 0067 * development environment on the PC, you're all set. Or if you're on the Mac 0068 * with Metrowerks, Symantec or MPW with SC you're ok too. For UNIX it shouldn't 0069 * matter. 0070 0071 * Changes by sailesh on 9/26 0072 0073 * There are two symbols used in the declaration of the JNI functions 0074 * and native code that uses the JNI: 0075 * JNICALL - specifies the calling convention 0076 * JNIEXPORT - specifies export status of the function 0077 * 0078 * The syntax to specify calling conventions is different in Win16 and 0079 * Win32 - the brains at Micro$oft at work here. JavaSoft in their 0080 * infinite wisdom cares for no platform other than Win32, and so they 0081 * just define these two symbols as: 0082 0083 #define JNIEXPORT __declspec(dllexport) 0084 #define JNICALL __stdcall 0085 0086 * We deal with this, in the way JRI defines the JRI_PUBLIC_API, by 0087 * defining a macro called JNI_PUBLIC_API. Any of our developers who 0088 * wish to use code for Win16 and Win32, _must_ use JNI_PUBLIC_API to 0089 * be able to export functions properly. 0090 0091 * Since we must also maintain compatibility with JavaSoft, we 0092 * continue to define the symbol JNIEXPORT. However, use of this 0093 * internally is deprecated, since it will cause a mess on Win16. 0094 0095 * We _do not_ need a new symbol called JNICALL. Instead we 0096 * redefine JNICALL in the same way JRI_CALLBACK was defined. 0097 0098 ******************************************************************************/ 0099 0100 /* DLL Entry modifiers... */ 0101 /* Win32 */ 0102 #if defined(XP_WIN) || defined(_WINDOWS) || defined(WIN32) || defined(_WIN32) 0103 # include <windows.h> 0104 # if defined(_MSC_VER) || defined(__GNUC__) 0105 # if defined(WIN32) || defined(_WIN32) 0106 # define JNI_PUBLIC_API(ResultType) _declspec(dllexport) ResultType __stdcall 0107 # define JNI_PUBLIC_VAR(VarType) VarType 0108 # define JNI_NATIVE_STUB(ResultType) _declspec(dllexport) ResultType 0109 # define JNICALL __stdcall 0110 # else /* !_WIN32 */ 0111 # if defined(_WINDLL) 0112 # define JNI_PUBLIC_API(ResultType) ResultType __cdecl __export __loadds 0113 # define JNI_PUBLIC_VAR(VarType) VarType 0114 # define JNI_NATIVE_STUB(ResultType) ResultType __cdecl __loadds 0115 # define JNICALL __loadds 0116 # else /* !WINDLL */ 0117 # define JNI_PUBLIC_API(ResultType) ResultType __cdecl __export 0118 # define JNI_PUBLIC_VAR(VarType) VarType 0119 # define JNI_NATIVE_STUB(ResultType) ResultType __cdecl __export 0120 # define JNICALL __export 0121 # endif /* !WINDLL */ 0122 # endif /* !_WIN32 */ 0123 # elif defined(__BORLANDC__) 0124 # if defined(WIN32) || defined(_WIN32) 0125 # define JNI_PUBLIC_API(ResultType) __export ResultType 0126 # define JNI_PUBLIC_VAR(VarType) VarType 0127 # define JNI_NATIVE_STUB(ResultType) __export ResultType 0128 # define JNICALL 0129 # else /* !_WIN32 */ 0130 # define JNI_PUBLIC_API(ResultType) ResultType _cdecl _export _loadds 0131 # define JNI_PUBLIC_VAR(VarType) VarType 0132 # define JNI_NATIVE_STUB(ResultType) ResultType _cdecl _loadds 0133 # define JNICALL _loadds 0134 # endif 0135 # else 0136 # error Unsupported PC development environment. 0137 # endif 0138 # ifndef IS_LITTLE_ENDIAN 0139 # define IS_LITTLE_ENDIAN 0140 # endif 0141 /* This is the stuff inherited from JavaSoft .. */ 0142 # define JNIEXPORT __declspec(dllexport) 0143 # define JNIIMPORT __declspec(dllimport) 0144 0145 /* OS/2 */ 0146 #elif defined(XP_OS2) 0147 # ifdef __declspec 0148 # define JNI_PUBLIC_API(ResultType) __declspec(dllexport) ResultType 0149 # define JNI_PUBLIC_VAR(VarType) VarType 0150 # define JNI_NATIVE_STUB(ResultType) __declspec(dllexport) ResultType 0151 # define JNICALL 0152 # define JNIEXPORT 0153 # define JNIIMPORT 0154 # else 0155 # define JNI_PUBLIC_API(ResultType) ResultType 0156 # define JNI_PUBLIC_VAR(VarType) VarType 0157 # define JNICALL 0158 # define JNIEXPORT 0159 # define JNIIMPORT 0160 # endif 0161 # ifndef IS_LITTLE_ENDIAN 0162 # define IS_LITTLE_ENDIAN 0163 # endif 0164 0165 /* Mac */ 0166 #elif macintosh || Macintosh || THINK_C 0167 # if defined(__MWERKS__) /* Metrowerks */ 0168 # if !__option(enumsalwaysint) 0169 # error You need to define 'Enums Always Int' for your project. 0170 # endif 0171 # if defined(TARGET_CPU_68K) && !TARGET_RT_MAC_CFM 0172 # if !__option(fourbyteints) 0173 # error You need to define 'Struct Alignment: 68k' for your project. 0174 # endif 0175 # endif /* !GENERATINGCFM */ 0176 # define JNI_PUBLIC_API(ResultType) __declspec(export) ResultType 0177 # define JNI_PUBLIC_VAR(VarType) JNI_PUBLIC_API(VarType) 0178 # define JNI_NATIVE_STUB(ResultType) JNI_PUBLIC_API(ResultType) 0179 # elif defined(__SC__) /* Symantec */ 0180 # error What are the Symantec defines?
