[gl4java-usergroup] Mac Port: Fetching Function Pointer Dynamically (FindSymbol, ...)

[Sven G. <sgo...@ja...>]

No success ...

This piece of code,
should give us the function-pointer (funcPtr) !

Purpose:
	The function ptr is achieved dynamically out of the
	OpenGL implementation ...

But: It does not work ...

Ideas ?


#include <CodeFragments.h>

void * LIBAPIENTRY getGLProcAddressHelper(const char * func, int *
method,
                                          int debug, int verbose )
{
        void * funcPtr=NULL;
        int lmethod; ...
  

#ifdef __mac_os
        /* funcPtr = GetProcAddress(func); */
        static char buffer[256];
        Ptr glLibMainAddr;
        CFragConnectionID glLibConnectId;
        CFragSymbolClass glLibSymClass;
                       GetSharedLibrary ("OpenGLLibrary",
                                          kCompiledCFragArch
/*kPowerPCCFragArch */,
                                          kStubLibraryCFrag,
                                          &glLibConnectId,
                                          &glLibMainAddr,
                                          buffer);

        printf("GetSharedLibrary errMsg: %s\n", buffer);
        fflush(NULL);

        FindSymbol      (glLibConnectId, func, &funcPtr, & glLibSymClass
);

        /* With this peace, or without,
           just getting NULL ! :-(
	
        if(glLibSymClass == kTVectorCFragSymbol)
        {
                printf("should be found: symbol class equals
kTVectSymbol\n");
        } else {
                printf("should be NOT found: symbol class NOT equals
kTVectSymbol\n");
                funcPtr = NULL;
        }
        */
        fflush(NULL);

        CloseConnection(&glLibConnectId);

        lmethod=2;

#endif
