Basic I/O in Qt

I would like to read/write into memory the same way I would write into a fil开发者_JAVA技巧e (with a datastream). I couldn't find a suitable class for this, but I'm sure it exists. What is the name of such a class in the Qt framework?

Check out the classes that inherit from QIODevice.

I'm not 100% clear on what you want, but chances are it is there. For instance, it sounds like you want a QBuffer but if you're talking about writing to shared memory at the OS level, then this isn't the same.
