    Default QLocalSocket connection error

    Hi,

    I am using qlocalsocket to establish connection with another program on the same machine. The server has been wrote in c and it works fine.
    The client has been wrote in qt. (using qlocalsocket.)
    This is my simple example:
    LocalSocket socket;
    socket.connectToServer(“mySocket”);
    socket.open(QIODevice::ReadWrite);
    But I got erro like this: No such file or directory.
    I checked whether mySocket is created by server or not. It did.
    What could be the problem?
    Thanks, David

    Are you using a relative or absolute path to the socket?

    The two programs are in the same place. So I use relative path.
    By the way I tested the following:
    I wrote this:
    QLocalSocket *mySocket = new QLocalSocket();
    I got error: Resource temporarily unavailable

    So use an absolute one. It doesn't matter if they are in the same place or not. What matters is their current working directory.

    I searched a lot and I found that the problem may with the socket. I mean there may are too many socket in open mod.
