QSocketDevice: win32/x11 differences

[a550ee]

Hello!
I've stumbled upon udp broadcast code which works on win32 and didn't work in x11.

Packet sender defined this way:

QSocketDevice * udp = new QSocketDevice(QSocketDevice::Datagram);
#ifdef QTS_WIN32
#elif QTS_LINUX
    int one = 1; 
    setsockopt(udp->socket(), SOL_SOCKET, SO_BROADCAST, &one, sizeof(one));
#endif

QSocketDevice * udp = new QSocketDevice(QSocketDevice::Datagram);
#ifdef QTS_WIN32
#elif QTS_LINUX
    int one = 1; 
    setsockopt(udp->socket(), SOL_SOCKET, SO_BROADCAST, &one, sizeof(one));
#endif

To copy to clipboard, switch view to plain text mode 

and it broadcasts packets this way:

udp->writeBlock(some-data, some-data.length(), broadcast-address, port);

udp->writeBlock(some-data, some-data.length(), broadcast-address, port);

To copy to clipboard, switch view to plain text mode 

Packet receiver defined this way:

QSocketDevice * udp = new QSocketDevice(QSocketDevice::Datagram);
    if(!udp->bind(some-address, port))
    {..}
    QSocketNotifier * udpn = new QSocketNotifier(udp->socket(), QSocketNotifier::Read);
    connect( udpn, SIGNAL( activated(int) ), this, SLOT( receiveSomething() ) );

QSocketDevice * udp = new QSocketDevice(QSocketDevice::Datagram);
    if(!udp->bind(some-address, port))
    {..}
    QSocketNotifier * udpn = new QSocketNotifier(udp->socket(), QSocketNotifier::Read);
    connect( udpn, SIGNAL( activated(int) ), this, SLOT( receiveSomething() ) );

To copy to clipboard, switch view to plain text mode 

When packet received, receiveSomething() fires and receiver mines data this way:

QString some-data = QString(udp->readAll());

QString some-data = QString(udp->readAll());

To copy to clipboard, switch view to plain text mode 

Packet sender works on all platforms, but receiver only on win32. Does QSocketDevice on x11 need special initialization?

Problem solved. Adding udp->setBlocking( FALSE ) and binding receiver socket to empty QHostAddress() will do the trick.
