Dear Mr. Torokhov and Linux-Input Community, Greetings of the day !! :) I have not seen some good use of write function in input subsystem. I am trying find the good uses of write function in Input subsystem, but could not find the solution over internet. Can you please help in answering my query below: As you know, in evdev.c file, fops is defined as below struct file_operations evdev_fops = { .read = evdev_read, .write = evdev_write, ... } So in what cases, evdev_write function is used ? One case I can think of is that, it can be used in input device simulator to write the recorded data back into buffer.
