Answer 1

You are probably look for this:

[static] QString QHostInfo::​localHostName()

Returns the host name of this machine.

main.cpp

#include <QHostInfo>
#include <QDebug>

int main()
{
    qDebug() << QHostInfo::localHostName();
    return 0;
}

main.pro

TEMPLATE = app
TARGET = main
QT = core network
SOURCES += main.cpp

Build and Run

qmake && make && ./main

Output

"myhostname"

http://doc.qt.io/qt-4.8/qhostinfo.html

qDebug(QHostInfo::localHostName().toLocal8Bit());
