Read/Write a file

I see there is a IWriteFile, but there is no method to read it.

Is there a way to open a file once and be able to read and write to it, without going native?

It seems a little silly to have a file you can write to, but then you cannot read back from it without opening the file in a reader.

To read a file:

Code: Select all

IReadFile *file = device->getFileSystem()->createAndOpenFile("text.txt");

then use file->read() to read the contents

use file->drop() to close the file when youre done

Write a file is almost the same

Code: Select all

IWriteFile *file = device->getFileSystem()->createAndWriteFile("text.txt", false);

then use file->write() to write to it

use file->drop() to close the file when youre done

Oh, I thought that it's a question for an IReadWriteFile?!

I was hoping for a file that I could read and write from at the same time, but I guess that is not part of the framework.

Is there a technical reason that reading from an IWriteFile is not supported?

Well, writing is not a typical task for games, besides several specialized occasions. And these are handled elsewhere, e.g. in the serialization part of the scene. What things are you planning to exchange via files?
