This theory practically depends on the critical section problem. After studying the overview of CSP, it's seen that there are lots of drawbacks in CSP but most of the different solutions are given by the different authors. But still no one has got the perfect solution to overcome this ...
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...
In a distributed system of N sites an efficient solution to the critical section problem is proposed to allow multiple simultaneous entries to the Critical Section. The proposed solution is token-based, deadlock-free and free from starvation. In all cases except during the book keeping cycle of...
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...

Q> Why can't critical section objects be used across processes compared to mutexes?Originally, I thought "Man, that's a silly question, it's obvious".But then I realized that it's not obvious, because critical sections are different from every other external synchronization mechanism in...
these sections. As a result of this, when a task enters a critical section, it is guaranteed that it will run until it exits from the region. A task should not go into a Blocked state inside a critical section, or it should not yield to ask the scheduler to perform context switching....
programming, we're quite surprised that Win32® critical sections haven't received very much "under the hood" attention. Sure, you probably know the basics of initializing and using critical sections, but have you ever taken the time to dig into the CRITICAL_SECTION structure defined in ...
This security update is rated Critical for all supported releases of Microsoft Windows (except Server Core installations, which are rated Important). For more information, see the subsection, Affected and Non-Affected Software, in this section....
