MPMT

A small library providing generic interface for multithreading across different platforms.
Created due to the fact that macOS does not support <threads.h> in C11.

See the documentation.

Features

• Mutex (Mutual exclusion)
• Cond (Condition variable)
• Thread (sleep, yield, etc.)
• Thread pool (tasks)
• Atomics (fetch add)

Usage example

void mutexExample()
{
    Mutex mutex = createMutex();

    if (!mutex)
        abort();

    lockMutex(mutex);
    // Do some synchronized work...
    unlockMutex(mutex);

    destroyMutex(mutex);
}

// ========================================

static void onUpdate(void* arument)
{
    volatile bool* isRunning = argument;
    
    while (*isRunning)
    {
        // Do some parallel work...
        sleepThread(0.001);
    }
}

void threadExample()
{
    volatile bool isRunning = true;

    Thread thread = createThread(
        onUpdate, &isRunning);

    if (!thread)
        abort();

    isRunning = false;
    joinThread(thread);
    destroyThread(thread);
}
