using sys_chmod
Hi,
I am trying to use sys_chmod in my kernel module to change the permission of a file. But i am getting sys_chmod undefined error, while trying to compile.
Googled for this, but not able to get this resolved. Are there any steps we should follow inorder to use sys_chmod?
My linux kernel version is 2.6.24.
Thanks,
|

You provides less information. You need to be more specific. What command you tried to compile, which OS you're using, etc.?

you know posting an error message alone is not a good idea. You would better post also your files or links (if they available on the net), the commands and the whole output.
I think this time you missed an #include somewhere, but I'm not really sure, there can be other problem as well.

In simple terms, post all the commands you tried and their outputs here.
