Chapter 4. Concurrent Programming
The future of programming is concurrent programming. Not too long ago, sequential, command-line programming gave way to graphical, event-driven programming, and now single-threaded programming is yielding to multithreaded programming.
Whether you are writing a web server that must handle many clients simultaneously or writing an end-user application such as a word processor, concurrent programming is for you. Perhaps the word processor checks for spelling errors while the user types. Maybe it can print a file in the background while the user continues to edit. Users expect more today from their applications, and only concurrent programming can deliver the necessary power and flexibility.
Delphi Pascal includes features to support concurrent programming—not as much support as you find in languages such as Ada, but more than in most traditional programming languages. In addition to the language features, you can use the Windows API and its semaphores, threads, processes, pipes, shared memory, and so on. This chapter describes the features that are unique to Delphi Pascal and explains how to use Delphi effectively to write concurrent programs. If you want more information about the Windows API and the details of how Windows handles threads, processes, semaphores, and so on, consult a book on Windows programming, such as Inside Windows NT, second edition, by David Solomon (Microsoft Press, 1998).
