The first known correct software solution to the critical-section problem for two threads was developed by Dekker. The two threads, T0 and T1, share the following variables:Boolean flag[2]; /* initially false */int turn;The structure of thread Ti (i=0 or 1), with Tj (j=1 or 0) be...

The first known correct software solution to the critical-section problem for n processes with a lower bound on waiting of n - 1 turns was presented by Eisenberg and McGuire. The processes share the following variables: enum pstate fidle, want in, in csg; pstate flag[n]; int turn; All...
