WebFormal Definition of Critical Sections. The overlapping portion of each process, where the shared variables are being accessed. Necessary and sufficient conditions for a solution to the c.s. problem: Mutual Exclusion --- if is executing in one of its critical sections, no , , is executing in its critical sections. WebExit Condition: Every critical section must end with an exit condition which alerts the system regarding the exit. A solution to a critical section problem must satisfy three conditions; a) Mutual Exclusion: If a process A is executing in its critical section, then no other processes must execute in its critical section.
