![]() ![]() Message based Communication in IPC (inter process communication).Communication between two process using signals in C.C program to demonstrate fork() and pipe().Input-output system calls in C | Create, Open, Close, Read, Write.Program for Decimal to Binary Conversion.Test and Set Pseudocode – //Shared variable lock initialized to false Swap algorithm is a lot like the TestAndSet algorithm. ![]() Instead of directly setting lock to true in the swap function, key is set to true and then swapped with lock. So, again, when a process is in the critical section, no other process gets to enter it as the value of lock is true. and individual key initialized to false Swap Pseudocode – // Shared variable lock initialized to false However, again bounded waiting is not ensured for the very same reason.Īgain, out of the critical section, lock is changed to false, so any process finding it gets t enter the critical section. Unlock and Lock Algorithm uses TestAndSet to regulate the value of lock but it adds another value, waiting, for each process which checks whether or not a process has been waiting. A ready queue is maintained with respect to the process in the critical section. All the processes coming in next are added to the ready queue with respect to their process number, not necessarily sequentially. ![]()
