Hi:

I've tried chattr, error for chattr: Function not implemented while reading flags on movefile, I checked, said chattr can only modify however, I'm just built a text, while I check the information read however are nothing,,

1. So, if I want to locate file attributes cannot be deleted, do you have any other instructions? Don't say chmod, chmod certainly not, RWX and delete it doesn't matter,

2. If you have this kind of instruction, how to implement in c? There should be a similar API?
