Hello Ricky,
Is there a API that validates that a IFS folder name is valid before you create it? For example /root///test would be invalid.
Actually, "/root///test" is a valid IFS folder name. It's equivalent to "/root/test", the extra slashes are ignored.
I don't think there's an API that will validate a folder name. Remember, the syntax of an illegal folder name would be different in each filesystem, and many of the filesystems in the IFS aren't actually on the iSeries, but are on a different machine that it connects to.
Not only that, but I can't actually think of a name that's not valid in the "root" and "QOpenSys" filesystem. I think pretty much every character except for "/" (which is still legal as a separator) and x'00' (which is the end of the string) is considered legal.
So, I think that the only way to really check if a folder can be created is to try it and find out. Obviously, you can check for errors on the mkdir() API and tell the user if it's illegal. But I'd expect errors like "you don't have authority" to be the reasons for failure, not the syntax of the name.
