Subject: [9fans] QTEXCL/DMEXCL redundancy
Date: Wed,  5 Dec 2012 09:41:48 +0000	[thread overview]
Message-ID: <af3d20ce-0b0c-45c5-b657-6ac5910ad865@googlegroups.com> (raw)

Hi all,

first time I am trying to create a "synthetic" file system.

I want to have "synthetic" files with the exclusive flag.

In my getdirent (called from dirread9p) function I have:

>d->qid = (Qid){n, 0, QTFILE|QTEXCL};
>d->mode = 0666;

This does not work (ls -l did not show 'l' flag).


When I made a modification:

>d->qid = (Qid){n, 0, QTFILE|QTEXCL};
>d->mode = DMEXCL|0666;

This works (ls -l shows 'l' flag).


I thought the DMEXCL in 'mode' is a unnecessary since QTEXCL is already present in 'Qid'. I was apparently wrong...

Can you recommend me e.g. the manual page or document explaining such matter?
I really do not understand why such a redundancy (QTEXCL/qid and DMEXCL/mode) is there...

Thanks.

Pavel
