_____________________________________________________________________________________| Fetch_And_Add(X, i) is a great atomic Read-Modify-Write instruction that reads the cost of memory area X, amounts it by value my spouse and i, and results the old worth of X. It is found in the pseudocode shown below to implement a busy-wait lock. T is an unsigned integer shared changing initialized to 0. The cost of 0 corresponds to lock getting available, whilst any nonzero value compares to the secure being unavailable. AcquireLock(L)

while (Fetch_And_Add(L,1))

L = 1;

ReleaseLock(L)

L = 0;

This rendering В A. | fails since L can overflow
