[Lazarus] Reading std::ostream from dll

Hi, I'm working with a dll/so created with C++, that has a function which
fills an std::ostream, and I need to read it from a FreePascal app using
a buffer or TStream.

The C++ method is similar to this:

void myClass::getOutputData(ostream &out);

I wrapped it to be readable from FPC as this:
extern "C"{
  void getMyOutputData(void * myInstance, void * &stream){
    myClass * lInstance = (myClass *)myInstance;

Is there a way to read std::ostream from FPC?

thanks in advance,
Leonardo M. Ramé
