There are functions copy_from_user and copy_to_user these are the functions which pass on data from user space to kernel space. You can use a command strace try to run it as follows strace firefox on terminal you will see a lot of output. > How the kernel load new memory area from the physical disk to RAM.

I know a book Linux Kernel Primer if you can get it ,it might help you. > Above questions may be unrelated or stupid. If so sorry for the > inconvenience. No question is stupid and when in doubt it is better to ask and get ridiculed at least you will learn some thing. > Thanks, > Prabhu > -- http://vger.kernel.org/vger-lists.html -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
