I have a executable that takes some arguments and sends n/w request and gets xml file/bytes as response. How do I execute this ?
On my CentOS, I execute it in terminal as
./myUtil --xml-output --password-file=myPassword --trf-downrate myUsername@my.serverName.com::home/
As a result, I get
<item trf_type="download" trf_rate="447.14kB/s"/>
How do I replicate the same from Qt program. Kindly help me with this.
Thanks.

Yeah, I tried the same.
For this
./myUtil --xml-output --password-file=myPassword --trf-downrate myUsername@my.serverName.com::home/
I tried like this
void CWorker::startProcess()
{
QString idevsUtil = "./idevsutil";
QStringList args = "--xml-output" << "--password-file=myPasswrd" << "--trf-downrate" << "myUsernameUser1@gmail.com@irs345.server.com::home/";
mProcess->startDetached(idevsUtil, args); // mProcess is a member variable allocated in constructor
}
// In main
CWorker worker;
worker.startProcess();
But I got error saying -
error: invalid operands of types 'const char [13]' and 'const char [26]' to binary 'operator<<'
I'm unable to crack this.

Yours Qt have disabled QString::QString ( const QByteArray & ba ) constructor. Read more in QString doc.

There is no operator << for character arrays:
"--xml-output" << "--password-file=myPasswrd" << "--trf-downrate" << "myUsernameUser1@gmail.com@irs345.server.com::home/"
I think you meant
QStringList args;
args << "--xml-output" << "--password-file=myPasswrd" << "--trf-downrate" << "myUsernameUser1@gmail.com@irs345.server.com::home/";

And just in case you have noticed by now: startDetached() is a static method.
