Một vài năm trở lại, hệ thống điều hành Macintosh được coi là sáng tạo và vui vẻ. Bây giờ nhiều người xem nó như là ngày và nặng cần viết lại chứ không phải là đơn giản nâng cấp. Windows 95 là hệ điều hành phổ biến nhất trên thế giới, nhưng hệ điều hành này là bằng nhiều cách khác một bản sao của hệ điều hành Mac, ít hơn của Mac ký tự. Nhiều lập trình viên và những người đam mê máy tính tận hưởng giao diện dòng lệnh sức mạnh của Unix Unix-nhưng không phải là gần đủ cho trực. | In this chapter Features of the BeOS Structure of the BeOS Software Kits and Their Classes BeOS Programming Fundamentals BeOS Programming Environment 1 BeOS Programming Overview A few years back the Macintosh operating system was considered innovative and fun. Now many view it as dated and badly in need of a rewrite rather than a simple upgrade. Windows 95 is the most popular operating system in the world but this operating system is in many ways a copy of the Mac OS less the Mac s character. Many programmers and computer enthusiasts enjoy the command-line interface power of Unix but Unix isn t nearly intuitive enough for the average end user. What users really want is an operating system that has an easy-to-use graphical user interface takes advantage of the power of today s fast microprocessor chips and is unencumbered with the burdens of backward compatibility. Enter Be Inc. and the BeOS the Be operating system. In this introductory chapter you ll learn about the features of the BeOS from a programmer s perspective. In particular you ll read about the terminology relating to the Be operating system. You ll also get an overview of the layout of the application programming interface or API that you ll be using to aid you in piecing together your programs. After the overview you ll look at some of the fundamentals of writing applications for the BeOS. No attempt will be made to supply you with a full understanding of the concepts techniques and tricks of programming for this operating system you ve got the whole rest of the book for that Instead in this chapter I ll just give you a feel for what it s like to write a program for the BeOS. Finally this chapter concludes with a first look at Metrowerks CodeWar-rior the integrated development environment you ll be using to develop your own applications that run on the BeOS. Features of the BeOS With any new technology comes a plethora of buzzwords. This marketing hype is especially true in the computer industry .
