hai all, I want to trace the files opening by users.i traced the systemcall sys_open and I wrote a code to display the filename.I thought that when the user is opening the file,it calls sys_open ,permission checking ..all r performed.So I displaed the filename(sys_open(const char *filename,int flags,int mode)).But it is displaying continuosly /dev/cdrom..why /dev/cdrom is coming in the picture? And What is the bestway to trace the the files opening by user,reading,modyfing etc... Please help me.I woulb be very thankful.Thanx in advance Kannan Ram _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp - Kernelnewbies: Help each other learn about the Linux kernel.
