Want FDs Receiver Example
Demonstrates receiving file descriptors passed to the application through a want.
The window logs every received want. For each entry in QOhosWant::fds the example prints the key, the descriptor value and the dev / ino numbers obtained with fstat, so they can be compared with the sender's log. Wants are handled both from QOhosAppContext::getAppLaunchWantInfo() at startup and from the QOhosAbilityContext::newWantInfoReceived() signal at runtime.
