Struct `core.sync.event.Event`

represents an event. Clients of an event are suspended while waiting for the event to be "signaled".


						
				struct Event
				;

Implemented using pthread_mutex and pthread_condition on Posix and CreateEvent and SetEvent on Windows.

import core.sync.event, core.thread, std.file;

struct ProcessFile
{
    ThreadGroup group;
    Event event;
    void[] buffer;

    void doProcess()
    {
        event.wait();
        // process buffer
    }

    void process(string filename)
    {
        event.initialize(true, false);
        group = new ThreadGroup;
        for (int i = 0; i < 10; ++i)
            group.create(&doProcess);

        buffer = read(filename);
        event.set();
        group.joinAll();
        event.terminate();
    }
}

Constructors

Methods

Name	Description
`initialize` (manualReset, initialState)	Initializes an event object. Does nothing if the event is already initialized.
`reset` ()	Reset the event manually
`set` ()	Set the event to "signaled", so that waiting clients are resumed
`terminate` ()	deinitialize event. Does nothing if the event is not initialized. There must not be threads currently waiting for the event to be signaled.
