[SOLVED] QFile and qrc files = bad file descriptor

MaxL

Hi everyone,

I have an issue with QFile when opening a file found in my qrc file.
What i'd like to do is to have a file descriptor on a file located in a qrc file.

I successfully open in ReadOnly mode my file but when i ask for the handle I always get -1, is there anyway to get the file descriptor ? or it is simply impossible ?

Thanks :)

QFile file("foo.bar");
file.open(QIODevice::ReadOnly);
int fileHandle = file.handle();

FILE* f = fdopen(fileHandle, "r");

Are you sure that code above is not working for your setup?

Hi,

@tucnak, It's not the same setup

A file retrieved from Qt's resources is not the same a file from your own filesystem.

However, there's a workaround for that, you can use QTemporaryFile. Open a temporary file, write the content of your resource in it and then use it for whatever you need.

Hope it helps
