How to extract and compress a cpio archive file in Qt

[sarode]

Hi,

Tried the other option specified the following output.

QStringList arguments1;
  arguments1 << "-i" << "<filename_with_absolute_path";
  // other option
 //  arguments1 << "-i" << "<" << "filename_with_absolute_path";
 
    proc1->start("/usr/bin/cpio", arguments1);
 
    if(!proc1->waitForFinished())
           qWarning("Returned");
 
    connect(proc1, SIGNAL(started()), this, SLOT(readData()));
 
void Process::readData()
{
    qWarning("Started");
}

QStringList arguments1;
  arguments1 << "-i" << "<filename_with_absolute_path";
  // other option
 //  arguments1 << "-i" << "<" << "filename_with_absolute_path";

    proc1->start("/usr/bin/cpio", arguments1);

    if(!proc1->waitForFinished())
           qWarning("Returned");

    connect(proc1, SIGNAL(started()), this, SLOT(readData()));

void Process::readData()
{
    qWarning("Started");
}

To copy to clipboard, switch view to plain text mode 

I got the following output. the process is able to start when i checked for the pid of the process, the state of the process is also S+ in #pa ax

The program halts with following output
Returned
QProcess: Destroyed while process is still running.

I am not able to understand, can we read the output generated by any buffer?
