Detailed Description

Synchronization primitives.

Locks, latches, and other synchronization primitives for coordinating between threads.

Example: Latch for Thread Coordination

#include <dispenso/latch.h>
#include <dispenso/parallel_for.h>
 
dispenso::Latch latch(4);  // Wait for 4 threads
 
dispenso::parallel_for(0, 4, [&](size_t) {
    // Do initialization work...
    latch.arrive_and_wait();  // Synchronize before continuing
    // All threads proceed together from here
});

Example: RWLock for Reader/Writer Access

#include <dispenso/rw_lock.h>
 
dispenso::RWLock lock;
std::vector<int> sharedData;
 
// Reader (multiple allowed concurrently)
{
    std::shared_lock<dispenso::RWLock> guard(lock);
    int value = sharedData[0];
}
 
// Writer (exclusive access)
{
    std::unique_lock<dispenso::RWLock> guard(lock);
    sharedData.push_back(42);
}
