Using QFile on a open linux file descriptor

[DBoosalis]

I have a feeling some one must have asked this before but darn if I could find it. I have File Descritpor (int value) . Can I convert that to a QFile. I see QFile::open(int OpenMode); but this file is already open. Anyone know if it is possible, and if it is possible can you tell me how

Any advise appreciated.

ps this is with QT 4.8

There are several obvious QFile::open() overloads taking FILE* integer file descriptors

Yes, but do they assume the file desciptor is not open already. Because I tried doing a QFIle open but the readyRead signal never gets emitted when I know data has been written to the file

QFile won't do that even for files entirely managed by Qt.
