I am trying to capture the Stdout from a process run through KProcess.

I set the signal handler up as follows:

    connect (&profile_generator, SIGNAL (receivedStdout (KProcess*, 
char*, int)), this, SLOT (gprofStdout (KProcess*, char*, int)));
      
then call

    profile_generator.start (KProcess::Block, KProcess::AllOutput);

and handle the returned value in

void KProfWidget::gprofStdout (KProcess *, char *buffer, int buflen)
{
    cout << buffer << endl;
    mGProfStdout += QString::fromLocal8Bit (buffer, buflen);
}

The buffer being returned and displayed is corrupted, here is an example:

               0.00    0.00     8íÿ¿¢ 327/601319      
vnl_diag_matrix<double>::operator()(unsigned int, unsigned int) [9]
                                       ^^^^ corruption

This occurs at various points throught the string (this example is 8248 
bytes long, although buflen is 1024)

This is with KDE 3.0.2 under Redhat 7.3.92 (Limbo) - same under 7.3.

Does anyone have any idea what is going on?

Thanks

Colin
