[fuse-devel] CUSE: get UID and PID of the process performing the operation

[Stefan S. <dev...@gm...>]

Hi,

in the FUSE API FAQ, it says that one can get the pid and the uid of the
process performing the filesystem operation by using:

	fuse_get_context()->uid, etc.

It appears that this only applied for FUSE, but not for CUSE, right ?

In my CUSE code I included <fuse.h> and tried to to get the PID and the UID.
However, both fields are always zero.

Is there a way to get this information for CUSE devices ?

Best Regards,
Stefan

I also get 0 in some cases or "random" numbers changing on each system call.

I think I just got it.
Instead of fuse_get_context(), you need to:

fuse_req_ctx(req)->uid, pid, etc.
