If a variable foo is not declared as volatile, then in the case of a compiler optimization, if you use Foo for the second time, the code generated by the compiler may use the value already stored in the register instead of "reload" the variable from

Volatile Introduction Volatile is similar to the well-known const and is also a type modifier. Volatile indicates to the compiler that the objects it modifies should not be optimized. Volatile is used for multithreaded programming. In a single

In some simple examples, for example, to assign a value to a field or increment the field, we need to synchronize the thread,Although the lock can meet our needs, a competitive lock will certainly lead to blocking, and then endure the thread context

Multi-thread lock system (II)-volatile, Interlocked, ReaderWriterLockSlim, interlocked  Introduction The previous chapter mainly describes the direct use of exclusive locks. However, it is too wasteful to use all the locks in practice, or the

1.volatile Volatile is primarily used to synchronize variables in multiple threads.Under normal circumstances, to improve performance, each thread saves a variable in its main memory as a copy of the variable in its own memory at run time, but this

IntroducedThe above chapter mainly says the direct use of exclusive locks. But all of the actual use of locks and too wasted, or the exclusive lock granularity is too large. This time we're talking about escalation locks and atomic
