| n | Remarks: |
||||||||||||
| u | Putting signal(N)
inside the CS of the producer |
||||||||||||
| (instead of
outside) has no effect since the |
|||||||||||||
| consumer must
always wait for both |
|||||||||||||
| semaphores before
proceeding |
|||||||||||||
| u | The consumer must
perform wait(N) before |
||||||||||||
| wait(S),
otherwise deadlock occurs if consumer |
|||||||||||||
| enter CS while
the buffer is empty |
|||||||||||||
| n | Using
semaphores is a difficult art... |
