When you are finished using the memory, you should free it with g_slice_free1() so that it can be used by another part of your application. This function frees a memory block of size SLICE_SIZE, located at strings[i]. g_slice_free1 (SLICE_SIZE, strings[i]); Internally, memory will be freed using the same method as it was allocated. Therefore, to use this function, you must have allocated the memory with g_slice_alloc() or g_slice_alloc0(). When you need to allocate only a single instance of an object, g_slice_new() is available. An example of using this function to allocate one object is shown in Listing 6-2. Listing 6-2. Allocating a Single Object typedef struct { GtkWidget *window; GtkWidget *label; } Widgets; Widgets *w = g_slice_new (Widgets); /* Use the structure just as you would any other structure. */ w->window = gtk_window_new (GTK_WINDOW_TOPLEVEL); w->label = gtk_label_new ("I belong to widgets!"); /* Free the block of memory of size "Widgets" so it can be reused. */ g_slice_free (Widgets, w);

If you need to allocate a single block of memory with a slice allocation, instead of using the method presented in Listing 6-1, you can call g_slice_new(). This function is defined as follows; it casts the value returned by g_slice_alloc() as the desired type. #define g_slice_new(type) ((type*) g_slice_alloc (sizeof (type))

You ll have multiple clients accessing the same data, and if the data is updated, then you ll need synchronization The best strategy when developing singletons is to consider the data mostly read-only This means the data from the singleton will be read-only for the most part and occasionally modified If a singleton ends up being read-write, then most likely you don t need a singleton, but a producer-consumer A type of producer-consumer is implemented in the next section..

You can put both native classes and types and managed classes and types in the same assembly in pure and mixed mode This is useful if you want to expose native classes and types to other NET languages such as C# or Visual Basic A typical scenario might be that you would take a native class library s source code, recompile it with the /clr option, and, in the same assembly, add managed classes that wrap the native classes that you want to export to other managed languages These managed wrappers would be marked public and would be visible to the other language However, the native classes in the DLL would not be accessible to the clients who use the assembly To support all this, there are various language features and CLR features Cross-language interop, P/Invoke, and COM interop are CLR features.

In addition to g_slice_new(), GLib provides g_slice_new0(), which uses g_slice_alloc0() to initialize the returned slice to 0. After you are finished with the memory, you need to free it. Since we only allocated one piece of memory in Listing 6-2, we can use g_slice_free(), which freed one piece of memory of the size Widgets and at the location w.

A Multithreaded Singleton Implementation The singleton implementation is multithreaded and manages the updates as necessary, and the full implementation is as follows: public class Singleton< singletonupdate, type> where singletonupdate: ISingletonBuilder< type>, new() where type : class { private static Singleton< singletonupdate, type> _instance; private ISingletonBuilder< type> _builder; private type _data; private ReaderWriterLock _lock; Thread _thread; private Singleton() { _builder = new singletonupdate(); _lock = new ReaderWriterLock(); _thread = new Thread( new ThreadStart( SingletonThread)); _thread.Start(); } private void SingletonThread() { while( _builder.KeepPolling) { try { _lock.AcquireReaderLock( -1); if( _data != null && !_builder.IsValid( _data)) { _lock.UpgradeToWriterLock( -1); _data = null; } } finally { _lock.ReleaseLock(); } Thread.Sleep( _builder.SleepTime); } } public static type Instance( object obj) { if( _instance == null) { lock( typeof( Singleton< singletonupdate,type>)) { if( _instance == null) { _instance = new Singleton< singletonupdate, type>(); } } } type retval = null; try {
