Kas saaks selgitada interlocked kontseptsiooni ja selle rakendamist mitme lõimega programmeerimises?

Interlocked is a collection of atomic operations in C# that ensures safe modification of shared data in a multithreaded environment without using heavy locks.

The main interlocked operations include:

• Increment/Decrement — atomic increase or decrease of a value.
• CompareExchange — compare and swap the value if it equals the expected value.
• Exchange — swap the value with a new one.

Using interlocked helps avoid race conditions when updating variables such as counters or flags, ensuring correctness and performance.

Example of usage:

int counter = 0;

// Atomic increment of the counter
Interlocked.Increment(ref counter);

// Atomic compare and swap
int original = Interlocked.CompareExchange(ref counter, 10, 5);

Thus, interlocked is a low-level tool for safe working with shared data in multithreaded programming.
