Function scopedMutexLock

Performs RAII based locking/unlocking of a mutex.


							
					ScopedMutexLock!M scopedMutexLock(M)
					(
					

					  M mutex,
					

					  LockMode mode = LockMode.lock
					

					)
					

					if (is(M : Mutex) || is(M : Lockable));
					

					

					ScopedMutexLock!(shared(M)) scopedMutexLock(M)
					(
					

					  shared(M) mutex,
					

					  LockMode mode = LockMode.lock
					

					)
					

					if (is(M : Mutex) || is(M : Lockable));

Note that while TaskMutex can be used with D's built-in synchronized statement, InterruptibleTaskMutex cannot. This function provides a library based alternative that is suitable for use with all mutex types.

Example

import vibe.core.core : runWorkerTaskH;

__gshared int counter;
__gshared TaskMutex mutex;

mutex = new TaskMutex;

Task[] tasks;

foreach (i; 0 .. 100) {
	tasks ~= runWorkerTaskH(() nothrow {
		auto l = scopedMutexLock(mutex);
		counter++;
	});
}

foreach (t; tasks) t.join();

assert(counter == 100);
