Re: Accessing one shared library globals from other

[hv reddy]

Dear Lionscribe,
Thanks for your reply.
In first library the address of globals is stored in
SysLibTblEntryType * libEntryP;
libEntryP->globalsP
globalsP is a void pointer.

so i tried to pass this globalsP to  the funstion in second  library.

but if i run the application it is crashing.


extern Err ECLib1Sub(UInt16 refNum,void    *G1Ptr,int x, int y,double *result)
    ECLIB1_LIB_TRAP(sysLibTrapBase + 6);
i called the function in second lib as follows

 ECLib1Sub(ECLib1Ref,&(libEntryP->globalsP),11, 1,&testsub);
 
and in second library in  ECLib1Sub function i am doing as follows.


Err ECLib1Sub(UInt16 refNum,void *G1Ptr,int x, int y,double *result)
{
  
  
  
  SysLibTblEntryType * TlibEntryP;
  
  ECLibGlobalsType *Tgp=NULL;// ECLibGlobalsType is first lib globals
   
   
Tgp =(ECLibGlobalsType *)(G1Ptr);

if(Tgp)
  {
  Tgp->x=1000;
  Tgp->y=1000;
 }



  *result= (double)(1111);

return errNone;
}



Am i doing any thing wrong.

I did by passing the first lib refernce and from it i can access first lib 
globals.
but i couldn't as the above way.

thanks for your help.


Regards,
Hvr
