@mbuf Hi,
In the function int (*open) (struct inode *inode, struct file *filp); for opening devices, what does the inode and filp point to. These structures are not defined in our code, are they supplied by the user space application trying to access the device? Does the inode refer to the /dev/<my char device> file, one of whose field is struct cdev *i_cdev; What is this filp? Please help.
