Figure 13.6 is a listing of code intended for use on the eCos kernel.

 a. Explain the operation of the code. Assume thread B begins execution first and thread A begins to execute after some event occurs.

 b. What would happen if the mutex unlock and wait code execution in the call to cyg_cond_wait, on line 30, were not atomic?

 c. Why is the while loop on line 26 needed?
