WebCandidate solutions to the critical section problem. To simplify the discussion we consider only two threads. Note these arguments work for threads and processes and the classic CS literature discusses these problem in terms of two processes that need exclusive access (i.e. mutual exclusion) to a critical section or shared resource.

WebThis code is a demo that how a process can enter into the critical section. The lock variable in the program is initially set with 0. When a process tries to enter into its critical region, then it first tests the value of the Setlock variable. if the SetLock value is set as 0, the process will change it to 1 and enters into the critical section. north florida gaming association tallahasseeWebPeterson's solution is a classic solution to the critical section problem.
