13-3: dup, ioctl, and fcntl #16

Open hark130 opened 4 months ago

  1. Design a new SKID library name to encapsulate this work
  2. Create a skid_file_descriptor_control.h
  3. Create a skid_file_descriptor_control.c
  4. Write a build rule
  5. Write some tests

Add functions for these "demonstrate the proper use of..." objectives:

NOTE: You'll probably want to add a generic open() implementation somewhere?

This has a good, practical rundown of ioctl usage. This seems to have some good code examples.

SPOILERS: There's a character driver requirement in the JQR line items so maybe save the ioctl work until then? Doubly so if there's a LKM line item.
