<Li> Unfortunately the consumer wasn't yet sleeping, and the wakeup call is lost . When the consumer resumes, it goes to sleep and will never be awakened again . This is because the consumer is only awakened by the producer when itemCount is equal to 1 . </Li> <Li> The producer will loop until the buffer is full, after which it will also go to sleep . </Li> <P> Since both processes will sleep forever, we have run into a deadlock . This solution therefore is unsatisfactory . </P> <P> An alternative analysis is that if the programming language does not define the semantics of concurrent accesses to shared variables (in this case itemCount) without use of synchronization, then the solution is unsatisfactory for that reason, without needing to explicitly demonstrate a race condition . </P>

Give solution to the producer–consumer problem using shared memory
