Linux Driver Read File at Eva Murnin blog

Linux Driver Read File. The read method is used to read data from a file or device. In the context of a character device driver, it is responsible for reading data. Therefore, their prototypes are pretty similar and it’s worth introducing them at the same time: These files are grouped into the /dev directory, and system. Ssize_t (*read) (struct file *, char *, size_t, loff_t *); Simple kernel module device numbers and device files create device file in driver and callbacks The read and write methods perform a similar task, that is, copying data from and to application code. A character device is one of the simplest ways to communicate with a module in the linux kernel. Used to retrieve data from the device. In unix, hardware devices are accessed by the user through special device files. Note also that, on some flavors of un*x, there are character special files for storage devices; A read or a write to the special file. These devices are presented as special files in a /dev directory and support. 43 rows in this repo you can find examples for:
