# Device model
> I found these structures while searching through the kernel
## Device Struct
- name
- get_tty : this is a member only used by TTY devices. This seems to be a dirth hack planned to be removed
- init : Called to initialize the device
- open : Call to open the device, called with a minor ID and a pointer to an allocated file structure[^1]
};
## File Operation struct
This is related to devices which seems to have a file structure/allocated file to them. Some function pointers can be NULL if the related operation can't be done to this device/file (read or write)
- release : "Close" the opened file in this instance (Release it)
- read
- write
- lseek
- ioctl : Is that for setting up the file/device?
[^1]: For instance giving to the display a pointer to the "/dev/display" file?
\ No newline at end of file
