Using the Generic Producer-Consumer is nearly identical to using the Windows Forms Invoke method, as shown in the following example: [TestFixture] public class TestProducerConsumer { delegate void TestMethod(); void Method() { Console.WriteLine( "Processed in thread id (" + Thread.CurrentThread.ManagedThreadId + ")"); } [Test] public void TestSimple() { IProducerConsumer producer = new ThreadPoolProducerConsumer(); Console.WriteLine( "Sent in thread id (" + Thread.CurrentThread.ManagedThreadId + ")"); producer.Invoke( new TestMethod( Method)); } } The TestSimple method instantiates ThreadPoolProducerConsumer type. Then the method Invoke is called using the delegate TestMethod, which executes the method Method. With respect to Windows Forms, a different type is instantiated, but the same Invoke method is used. The implementation is also a bit different in that the consumer isn t a single thread, but as many threads as necessary.

For any nontrivial parameter types, there is the issue of correctly marshaling the parameters P/Invoke is not very type safe, as the compiler s ability to detect incorrect marshaling conversions is limited Finally, P/Invoke requires a lot of extra work for nontrivial parameter types, because the types that the native API uses need to be redefined in managed code If you instead use other interop methods described later in this chapter, you can simply include the relevant header files that define all the types used in the parameter list, and not only avoid the trouble of re-creating them in managed code, but in many cases avoid the context switch to native code and vice versa You also can take advantage of the marshaling library, further simplifying your job of converting the parameter types.

Caution Timeout functions can be delayed by function calls with a higher priority and how long it takes to

run the callback function. Therefore, it cannot be relied on as a source of precise timing. If a timeout gets behind in time, the next call will recalculate the interval. The function will not try to make up lost time from delays.

When I first started writing this chapter, I wondered what I was going to write. Sure, the material on immutable classes, reader-writer processes, flyweights, and so on was plentiful. My doubts were how to present this material to make it obvious that you need to implement these things in your daily development. What I was especially concerned with was the topic of immutability.

Still, if you do need to use P/Invoke, you should avail yourself of Internet resources for P/Invoke programming, such as wwwpinvokenet, which includes prepared code for many Win32 calls Before we get to the alternatives to P/Invoke, it will help for you to learn about the new marshaling library..

The third parameter in g_timeout_add_full() is the actual timeout function. Timeout functions receive a gpointer and return a gboolean value. By returning FALSE from the timeout function, it will be removed. The gpointer parameter is defined by the fourth parameter of g_timeout_add_full(). The last parameter defines a destroy function that should be called when the idle function is removed, which occurs when FALSE is returned from the idle function. It is safe to set this parameter as NULL.

It s one of those topics that sounds good (for example, eat healthy, exercise daily, don t smoke, etc.), but due to real-life circumstances and contexts is hard to realize. Yet after using the techniques discussed in this chapter, I m convinced of the advantages of immutability, flyweights, and so on. What especially surprised me are the advantages of immutable objects in a multithreaded context. While investigating the implementation of the string class, I was awed at how sophisticated .NET strings are, and yet very fast. Also interesting was the implementation of the producer-consumer in Windows Forms. Overall, the message is that to be able to write effective multithreaded applications, immutability, flyweights, reader-writer, producer-consumer, and object pools are patterns and techniques that you need. And with CPU producers such as Intel and AMD producing multicore CPUs, that need to write effective multithreaded applications will become ever more vital.

Destroy functions defined in g_timeout_add_full() should not return any value, but do receive a gpointer as their parameter. This gpointer is the same value originally received by the timeout function, which gives you an opportunity to free it from memory if necessary.
