What is _Atomic?
The _Atomic qualifier, introduced in C11, marks a variable so that reads and writes to it happen as a single, indivisible operation, even when accessed from multiple threads. This prevents data races on that variable without needing a separate lock. It is used together with the <stdatomic.h> header when writing concurrent C code.
