QFile::handle

Message 1 in thread

Hi all,

With Qt3 QFile had a method handle() which returned an integer with the
bare file handle of an open file.

I am looking for something like this in Qt4.

Best regards,

Andre

What's wrong with Qt4's "int QFile::handle()" ?

Be aware that this function does return -1 when opening a QFile in windows.

It only returns a valid file handle when using
bool QFile::open ( FILE * fh, OpenMode mode ) or
bool QFile::open ( int fd, OpenMode mode )



The documentation does not mention this with a single word. :(

And while I write this and read the source of Qt 4.3.4 I saw that it was 
fixed. Strange - I'm sure it was rejected when I wrote to qt-bugs some 
months ago...


Sorry for the noise,

It's broken on Windows. I'm going to fix it for 4.4.1.
