If you're running with Visual C++, Symantec C, or Borland's * development environment on the PC, you're all set. Or if you're on the Mac * with Metrowerks, Symantec or MPW with SC you're ok too. For UNIX it shouldn't * matter. * Changes by sailesh on 9/26 * There are two symbols used in the declaration of the JNI functions * and native code that uses the JNI: * JNICALL - specifies the calling convention * JNIEXPORT - specifies export status of the function * * The syntax to specify calling conventions is different in Win16 and * Win32 - the brains at Micro$oft at work here. JavaSoft in their * infinite wisdom cares for no platform other than Win32, and so they * just define these two symbols as: #define JNIEXPORT __declspec(dllexport) #define JNICALL __stdcall * We deal with this, in the way JRI defines the JRI_PUBLIC_API, by * defining a macro called JNI_PUBLIC_API. Any of our developers who * wish to use code for Win16 and Win32, _must_ use JNI_PUBLIC_API to * be able to export functions properly. * Since we must also maintain compatibility with JavaSoft, we * continue to define the symbol JNIEXPORT. However, use of this * internally is deprecated, since it will cause a mess on Win16. * We _do not_ need a new symbol called JNICALL. Instead we * redefine JNICALL in the same way JRI_CALLBACK was defined. ******************************************************************************/ /* DLL Entry modifiers... */ #if defined(XP_OS2) # ifdef XP_OS2_VACPP # define JNI_PUBLIC_API(ResultType) ResultType _System # define JNI_PUBLIC_VAR(VarType) VarType # define JNICALL _Optlink # define JNIEXPORT # else # define JNI_PUBLIC_API(ResultType) ResultType # define JNI_PUBLIC_VAR(VarType) VarType # define JNICALL # define JNIEXPORT # endif /* Win32 */ #elif defined(XP_WIN) || defined(_WINDOWS) || defined(WIN32) || defined(_WIN32) # include <windows.h> # if defined(_MSC_VER) || defined(__GNUC__) # if defined(WIN32) || defined(_WIN32) # define JNI_PUBLIC_API(ResultType) _declspec(dllexport) ResultType __stdcall # define JNI_PUBLIC_VAR(VarType) VarType # define JNI_NATIVE_STUB(ResultType) _declspec(dllexport) ResultType # define JNICALL __stdcall # else /* !_WIN32 */ # if defined(_WINDLL) # define JNI_PUBLIC_API(ResultType) ResultType __cdecl __export __loadds # define JNI_PUBLIC_VAR(VarType) VarType # define JNI_NATIVE_STUB(ResultType) ResultType __cdecl __loadds # define JNICALL __loadds # else /* !WINDLL */ # define JNI_PUBLIC_API(ResultType) ResultType __cdecl __export # define JNI_PUBLIC_VAR(VarType) VarType # define JNI_NATIVE_STUB(ResultType) ResultType __cdecl __export # define JNICALL __export # endif /* !WINDLL */ # endif /* !_WIN32 */ # elif defined(__BORLANDC__) # if defined(WIN32) || defined(_WIN32) # define JNI_PUBLIC_API(ResultType) __export ResultType # define JNI_PUBLIC_VAR(VarType) VarType # define JNI_NATIVE_STUB(ResultType) __export ResultType # define JNICALL # else /* !_WIN32 */ # define JNI_PUBLIC_API(ResultType) ResultType _cdecl _export _loadds # define JNI_PUBLIC_VAR(VarType) VarType # define JNI_NATIVE_STUB(ResultType) ResultType _cdecl _loadds # define JNICALL _loadds # endif # else # error Unsupported PC development environment. # endif # ifndef IS_LITTLE_ENDIAN # define IS_LITTLE_ENDIAN # endif /* This is the stuff inherited from JavaSoft .. */ # define JNIEXPORT __declspec(dllexport) /* Mac */ #elif macintosh || Macintosh || THINK_C # if defined(__MWERKS__) /* Metrowerks */ # if !__option(enumsalwaysint) # error You need to define 'Enums Always Int' for your project. # endif # if defined(TARGET_CPU_68K) && !TARGET_RT_MAC_CFM # if !__option(fourbyteints) # error You need to define 'Struct Alignment: 68k' for your project. # endif # endif /* !GENERATINGCFM */ # define JNI_PUBLIC_API(ResultType) __declspec(export) ResultType # define JNI_PUBLIC_VAR(VarType) JNI_PUBLIC_API(VarType) # define JNI_NATIVE_STUB(ResultType) JNI_PUBLIC_API(ResultType) # elif defined(__SC__) /* Symantec */ # error What are the Symantec defines?
