Hi, I am writing a kernel module in which I am trying to read the contents of a file into a buffer, but the buffer is still empty. Do you know why it is so? The code that I have is : fd = filp_open(filename,O_RDONLY, 0500); num_read = fd->f_op->read(fd, buffer , count, &fd->f_pos); I tried printing out the contents of buffer, but it is empty. But num_read has a value > 0. I would really appreciate a reply. Thanks, Femitha. >From: John Levon <moz@compsoc.man.ac.uk> >To: kernelnewbies@nl.linux.org >Subject: Re: Linux Kernal inconsistency? >Date: Sat, 10 Nov 2001 18:31:50 +0000 > >On Sat, Nov 10, 2001 at 04:56:30PM +0000, Dave Jones wrote: > > > Feel like writing this (and related trickery) up for a > > external-modules-howto for the webpages ? 8) > >yes I do. > >john > >-- >"I know I believe in nothing but it is my nothing" > - Manic Street Preachers >-- >Kernelnewbies: Help each other learn about the Linux kernel. >Archive: http://mail.nl.linux.org/kernelnewbies/ >IRC Channel: irc.openprojects.net / #kernelnewbies >Web Page: http://www.kernelnewbies.org/ > _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp -- Kernelnewbies: Help each other learn about the Linux kernel.
