/*******************************************************************************
* WHAT'S UP WITH THIS FILE?
*
* This is where we define the mystical JNI_PUBLIC_API macro that works on all
* platforms. 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.
