Adding multithreaded processing to your applications can make them faster and more responsive. The authors of Multithreaded Programming with Win32 show you how to take advantage of threads through practical, easy-to-understand examples.
The book begins with a history of threads, which were implemented rather recently (in 1979). They look at Win32 threads in particular, including all the APIs used to create and control threads. (Several of the sample programs here use graphics and even rudimentary games--such as a simple version of Pong.)
After you create threads, the authors teach you how to get them to work together. They do a fine job of explaining all the Win32 synchronization objects, such as mutexes, critical sections, and event objects, in a clear and concise style.
The strategies for coordinating threads have been well known in computer science for some time. The authors present common thread scenarios using the producer-consumer, bounded buffers, and readers-writers solutions. They explore the concept of thread monitors, for greater abstraction when controlling resources, and discuss deadlock analysis, with strategies to prevent threads from freezing.
Later, the book moves on to some programming strategies for allocating work between threads, using models like the workgroup, manager-worker, and pipeline to solve problems. The book closes with a few examples of threads used across the enterprise, including Microsoft's DCOM.
In all, this guide proves remarkably engaging and effective. The authors present many useful code examples of multithreading in action, which will get you started using threads in your own programs. --Richard DraganFrom the Inside Flap:
Preface In this book, we describe techniques for designing and implementing multithreaded software applications. Multithreaded programming can effectively improve efficiency and performance in an application program by introducing concurrency or parallelism. Until recently, concurrent programming required multiple processes, each with a single thread of execution, running concurrently on a multitasking operating system. In the past, concurrent programming was a tool used mostly by researchers and system implementors, that is, programmers of operating systems, networking, and other systems software. Modern operating systems like Solaris, AIX, DEC-UNIX, Windows 98, Windows NT, HP-UX, and Linux, all support multiple threads of control within the same address space. With the wide availability of multiprocessor computers in the coming years, multithreaded programming will be a viable and important technique for application programmers to master. With threads, a process can have multiple instruction streams executing simultaneously with much lower overhead than concurrent processes. Threads within the same address space inherently share that process's memory, which makes communication and data sharing among threads efficient. In addition, multithreading technology is absolutely essential for domains such as real-time multimedia and distributed systems. Andrew Birrell, in his excellent tutorial, Programming with Threads, lists five main benefits of multithreaded programming: (1) greater speed from multiprocessor computers, (2) improved program efficiency by avoiding waits associated with slow-speed I/O devices, (3) multiple inputs from a user at the same time, (4) simpler server programs, and (5) responsive programs with computations judiciously spread over time. Developing programs that exploit these benefits of multithreading, however, is a challenge; the presence of parallelism introduces a new set of problems like resource sharing, deadlocks, race conditions, and so forth. The purpose of this book is both to introduce you to the concept of multithreaded programming, and to demonstrate how some of these challenges can be overcome. We have tried to cover all the important aspects of multithreaded programming, and to create a book that you will want to read as a primer book and use later as a reference guide. Outline of Chapters Chapter 1 introduces the basic concepts, history, benefits, and challenges of multithreaded programming. To provide an immediate hands-on experience, this chapter presents a small multithreaded program for you to experiment with right away. Chapter 2 introduces the Win32 thread interface and discusses its use. Here we also discuss the concepts of processes and threads, illustrate thread management functions, describe thread priorities and scheduling, and examine synchronization objects. In Chapter 3 we discuss the fundamental techniques for synchronizing threads of a multithreaded application. Using classic concurrency problems of producer-consumer, bounded-buffer, and readers-writers, we demonstrate synchronization techniques using the threads interface described in Chapter 2. Chapters 4 and 5 introduce monitors, an important abstraction and tool for multithreaded programming. While Chapter 4 describes the structure and properties of monitors, Chapter 5 simulates monitors using a combination of C++ classes and Win32 synchronization objects. Once again, we use concurrency problems of producer-consumer, bounded-buffer, and readers-writers to illustrate and demonstrate the usefulness of monitors in these chapters. Chapter 6 covers system deadlock in detail. In this chapter, we describe conditions for deadlock and explore techniques for avoiding it. Using the classic dining philosophers' problem, we demonstrate how to apply several deadlock- handling techniques like deadlock detection and recovery, prevention, and avoidance to application programs. Chapter 7 surveys a variety of thread package architectures, including user-level threads, kernel threads, multiplexed threads, and scheduler activations. We describe the impact of each thread architecture on the design and implementation of multithreaded programs. Chapter 8 covers the important topic of how to break up an application into multiple threads. We present illustrative programming models, including work groups, manager-worker, deferred computation, pipeline, and WorkCrew. Each model is illustrated using a sample program. In Chapter 9 we describe how threads can be used in the client and server components of a distributed application. Multithreaded programming plays an important role in this domain. We show the basic steps for constructing a distributed application using Microsofts' Remote Procedure Call (RPC) and Distributed Component Object Model (DCOM). The concurrent programming techniques covered in this book are well known in the computer science research community and are discussed in technical publications and several operating system textbooks. These concepts have, however, only recently become available for application programmers. The target audience for this book are application developers who want to experiment with multithreaded programming, and who have a working knowledge of the C programming language. Some parts of the book require a knowledge of the C++ language and the Visual C++ programming environement. We do not describe the threads API of the Microsoft Foundation Classes (MFC). The examples have been implemented on Intel Pentium machines running the Windows NT 4.0 Workstation operating system. Also, for clarity and brevity of exposition, we have removed error-checking code from the listings presented in the book except where such code is essential to the content under discussion.
