C ++ Qt写入unix socket

Question

I have a unix socket in /tmp/my_sock

How can I connect to it and write data? Is there a Qt way to do it?

Answer 1

Qt supports unix domain sockets natively through QLocalSocket and QLocalServer .

The name you have to pass as first parameter to QLocalSocket::connectToServer is the socket path: "/tmp/my_sock" .

Answer 2

As of 2011 , Qt doesn't have any support for sockets at all, since Qt's moto is cross-platforming .

If you want to use sockets in your Qt program, you should implement socket communication via standard Linux functions, socket() , connect() , etc, or implement your own class based on QAbstractSocket .
