operate file in kernel space Yong Fan Sun Mar 25 20:00:21 2012
Hi all, I want to operate file in kernel space. At present, I have found the following kernel routines, which operate file: Kern_open(), kern_close(), kern_readv() and kern_writev(). Now, I have some doubt about these routines? 1 kern_open() doesn't return a file handle or file pointer? As we know, filp_open(), which is a Linux kernel routine, returns a file pointer. ZwCreateFile(), which is a Windows kernel routine, returns a file handle. 2 how can I "seek" a file in kernel space? The function of "seek" routine is similar with generic_file_llseek()(Linux) or ZwSetInformationFile()(windows).
