Hello, I have the following problem: I have a struct like this:

struct HSymTbl { unsigned long pSymTbl; unsigned long length; }; and I need to call the following function:

int LoadUser_HL(void ** hDev,char * FilePath,struct HSymTbl * pSymTable);

This way, I just to use a Structure subclass and pass my Structure object by reference, is it correct? I do it and works fine, but after I need to call the following function:

K_Move_Data_HL(void ** hDev,BOOL RW,unsigned short Nb_Words, unsigned short * Buffer,signed long DSPAddress, int MemSpace,char * Symbol,struct HSymTbl SymTable);

and here, I need do pass a Structure by value. How can I do it? I have already tried to implement the interfaces Signature.ByReference and Signature.ByValue, but I can not understand how to use the Signature SymTable as a reference in a moment and as value in another moment. May You might help me please?
