Critical Section and Mutual Exclusion A critical section is a section of code in which a process accesses shared resources. Thus, the execution of critical sections must be mutually exclusive (e.g., at most one process can be in its critical section at any time). The critical-section problem is to design a protocol that processes can use to cooperate. int count; // shared critical sections count++; count--; cout
The Critical Section Protocol do { entry section critical section exit section A critical section protocol consists of two parts: an entry section and an exit section. Between them is the critical section that must run in a mutually exclusive way. } while (1); 9
