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?
