<![CDATA[QHostInfo::localHostName() never give my hostname (archlinux)]]>why
qDebug() << QHostInfo::localHostName();
not show my hostname ?

From terminal, command "hostname" give me my hostname...
what's happen ? what i forget or misunderstand about QHostInfo ?
If QHostLocalHostName::localHostName() not show hostname fromlocalhost, what is the interest of this function ?
