Listing 18-7 shows how to create a thread static class variable. It involves nothing more than placing the attribute [ThreadStatic] in front of the variable that you want to make thread static. I added a little wrinkle to this example by making the static variable a handle to an integer. Because the variable is a handle, you need to create an instance of it. Normally, you would do that in the static constructor, but for a thread static variable this doesn t work, as then only the main thread s version of the variable has been allocated. To fix this, you need to allocate the static variable within the thread s execution. Listing 18-7. ThreadStaticVars.cpp Synchronizing Using the ThreadStatic Attribute using namespace System; using namespace System::Threading; ref class MyThread { public: [ThreadStatic] static int ^iVal; public: static MyThread() { iVal = gcnew int; }

Then, just to keep our code in a compilable state, switch over to DudelViewController.m and insert some empty implementations for those methods inside the @implementation DudelViewController section:

void ThreadFunc(); void SubThreadFunc(); }; void MyThread::ThreadFunc() { iVal = gcnew int; iVal = 7; SubThreadFunc(); } void MyThread::SubThreadFunc() { int max = *iVal + 5; while (*iVal < max) { Thread ^thr = Thread::CurrentThread; Console::WriteLine("{0} {1}", thr->Name, iVal->ToString()); Thread::Sleep(1); (*iVal)++; } } void main() { Console::WriteLine("Before starting thread"); MyThread ^myThr1 = gcnew MyThread(); Thread ^thr1 = gcnew Thread(gcnew ThreadStart(myThr1, &MyThread::ThreadFunc)); Thread ^thr2 = gcnew Thread(gcnew ThreadStart(myThr1, &MyThread::ThreadFunc)); Thread::CurrentThread->Name = "Main"; thr1->Name = "Thread1"; thr2->Name = "Thread2"; thr1->Start(); thr2->Start(); myThr1->iVal = 5; myThr1->SubThreadFunc(); }

Referencing a member variable by address is classified as unsafe, so to get this example to compile, you need to use the /clr:pure or just plain /clr option.

Access modifier (public, private, etc.) Any custom attributes that are applied to the class Read-only property containing the name of the file in which the class is located Read-only property that gives the full, namespace-qualified name of the class Read-only property that indicates if the class is a generic class (for more information, see Generics in the MSDN documentation) Read-only property that lists all of the interfaces implemented by this class

First off, when you comment out the [ThreadStatic] attribute and run the ThreadStaticVars.exe program, you get the output shown in Figure 18-8. Notice how the value is initialized three times and then gets incremented without regard to the thread that is running. Maybe this is what you want, but normally it isn t.

} } } } } (IBAction)popoverFontName:(id)sender { (IBAction)popoverFontSize:(id)sender { (IBAction)popoverStrokeWidth:(id)sender { (IBAction)popoverStrokeColor:(id)sender { (IBAction)popoverFillColor:(id)sender {

Figure 18-8. The attribute commented-out ThreadStaticVars.exe program in action Uncomment the [ThreadStatic] attribute and run ThreadStaticVars.exe again. This time you ll get the output shown in Figure 18-9. Notice now that each thread (including the main thread) has its own unique instance of the static variable.

Indicates how (if) this class can be inherited: None, Abstract (MustInherit in VB), Sealed (NotInheritable in VB), or Static (no equivalent in VB) (does not apply to structures) Read-only property indicating the base class of this class (does not apply to structures) The name of this class The name of the class file in which new members are added, for use with partial classes (for more information, see Partial Classes in the MSDN documentation) General comments about the class A summary of the class s purpose/functionality

Figure 18-9. The ThreadStaticVars.exe program in action Notice that the static constructor works as expected for the main thread, whereas for worker threads you need to create an instance of the variable before you use it. To avoid having the main thread create a new instance of the static variable, the class separates the logic of initializing the variable from the main logic that the thread is to perform, thus allowing the main thread to call the application s logic without executing the static variable s gcnew command.
