You are probably look for this:

[static] QString QHostInfo::localHostName()

Returns the host name of this machine.

#include <QHostInfo>
#include <QDebug>

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

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

qmake && make && ./main

"myhostname"
