CSPyInterpreter and std output

[pollyp]

Hi,

I've been reading the reference appendix on calling python scripts from within native applications. One thing I'd like to do is capture the script's output for processing within the native application -- how can I do that? Yes, I see the iStdO/I public prototypes and am guessing that they are part of the solution -- but how do I use them?

Thanks in advance!

Below some code snippets showing how to forward the output to a file:

// CMyTester.h:

/**
* File handle to script output
*/
RFile iResultFile;

/**
* Interpreter
*/
CSPyInterpreter* iInterpreter;

// CMyTester.cpp:

// Redirects output, called by the interpreter:
int CMyTester::CallSTDO(const char *buf, int n)
  {
  TPtrC8 from((TUint8*)buf);
  HBufC* tgt = HBufC::NewLC(n);
  TPtr data = tgt->Des();
  data.Copy(from.Left(n));

  TInt pos = 0;
  pTester->iResultFile.Seek(ESeekEnd, pos);
  pTester->iResultFile.Write(from.Left(n));

  CleanupStack::PopAndDestroy(); //tgt
  return n;
  }

// pTester is a pointer to CMyTester instance, this is needed for CSPyInterpreter
// instance to access the private file handle in CMyTester instance
pTester->iInterpreter->iStdO = (CallSTDO); //Forward IO
