language agnostic - How are mutexes implemented? - Stack ...

    https://stackoverflow.com/questions/1485924/how-are-mutexes-implemented
    How are mutexes implemented? Ask Question Asked 10 years, ... (If the hardware supports these.) If the mutex that you're using doesn't work at this kernel/hardware level then it can still be reliable but I would advise to not use it, unless there's no alternative. ... There's also some complexity added to support reentrancy on a single thread.

Mutual exclusion - Wikipedia

    https://en.wikipedia.org/wiki/Mutual_exclusion
    Enforcing mutual exclusion Hardware solutions. On uniprocessor systems, the simplest solution to achieve mutual exclusion is to disable interrupts during a process's critical section. This will prevent any interrupt service routines from running (effectively preventing a process from being preempted). Although this solution is effective, it ...

    Fast Mutexes and Guarded Mutexes. 06/16/2017; 4 minutes to read; In this article. Starting with Windows 2000, drivers can use fast mutexes if they require a low-overhead form of mutual exclusion for code that runs at IRQL <= APC_LEVEL. A fast mutex can protect a …

Lock (computer science) - Wikipedia

    https://en.wikipedia.org/wiki/Lock_%28computer_science%29
    In computer science, a lock or mutex (from mutual exclusion) is a synchronization mechanism for enforcing limits on access to a resource in an environment where there are many threads of execution.A lock is designed to enforce a mutual exclusion concurrency control policy.

Semaphores and Condition Variables

    Destroys the mutex. The behavior is undefined if the mutex is owned by any thread or if any thread terminates while holding any ownership of the mutex.

std::mutex::mutex - cppreference.com

    https://en.cppreference.com/w/cpp/thread/mutex/mutex
    Parameters (none) [] NoteBecause the default constructor is constexpr, static mutexes are initialized as part of static non-local initialization, before any dynamic non-local initialization begins.This makes it safe to lock a mutex in a constructor of any static object. [] See als
