Overview
|
|
********
|
|
|
|
A simple application that demonstrates basic sanity of the kernel.
|
|
Two threads (A and B) take turns printing a greeting message to the console,
|
|
and use sleep requests and semaphores to control the rate at which messages
|
|
are generated. This demonstrates that kernel scheduling, communication,
|
|
and timing are operating correctly.
