return value for WriteData() and other write commands

[Lebostein]

For example: I can't check the success of execution of WriteData() when my harddisk is full... I have no problem to create a file, when I have few free bytes on my disk. But when I write ab big memory block in this file I have a problem...

Actually, the function should return the number of bytes written (which can be part of the total size to write).

In 3.94b the function retruns 0 or 1. It's a random number? It means false or true? It's the number of written bytes? Please update the documentation!!!
