What are three conditions that a solution for the critical section problem must satisfy?

The three conditions are as following:-

a)      Mutual exclusion:- if a process is implementing in its critical section, then another processes aren't allowed to get in to their critical section till the first process exits from its critical section.

b)      Progress:- if no process is implementing in its critical section and some processes wish to enter into their critical section, after that only those processes that are not executing in their remainder section can participate in the decision on which will enter in its critical section next and this selection cannot be postponed indefinitely.

c)      Bounded waiting:- there subsist a bound on the number of times that other processes are allowed to enter their critical sections subsequent to a process have made a request to enter into its critical section and before that request is granted.
