Modify the kernel module you created in the \#3 Homework to introduce the ioctl mechanism that sets and gets messages.
|
||||
Compile and run the program.
|
||||
You should also write a user-space program that calls ioctl().
|
||||
Submit the source code and the screen shot of the result of execution displayed by the dmesg command.
