Subject: [OFFTOPIC] f_pos ?
Date: Sun, 04 Jul 2004 21:18:05 +0200	[thread overview]
Message-ID: <1088968685.2429.1.camel@localhost.localdomain> (raw)

Hi,
	
	I try to understand how readdir process works and I can't understand
f_pos management :

        Having in mind things work that way :

        user : ls
        glibc : 
                open (->sys_open)
                getdentries64 (->sys_getdentries64)
                
        kernel:
                sys_getdentries64
                ->vfs_readdir
                        ->ext2_readdir

At that point, I don't understand why ext2_readdir is playing with
filp->f_pos .... It should be 0 ...Why does it care about offset ?

Thanks in advance for your precious help,
FabF
