【摘要】 Linux系统现已广泛应用于各种嵌入式设备。Matchbox是在手持嵌入式系统中常用的开源窗口管理器。其自带的程序启动器不能很好的处理一个应用程序启动另一个应用程序的启动方式。为此,本文应用进程间通信(Inter-Process Communication-IPC)构建后台服务进程(Service),改进了嵌入式Linux操作系统的程序启动机制,实现了更加完善的启动方式,避免了可能发生的错误。同时提高了程序的可理解性,可读性,减少了程序的重复性和耦合性,也使其能更好的应对新的需求。更多还原

【Abstract】 Linux is broadly used in various embedded system now.Matchbox is a kind of open source window manager which is used in hand-held embedded system.The application launcher of it cannot deal well with the launch method that one application launches another.So,this paper uses Inter-Process Communication to establish background service process.This improves the app-launch mechanism of embedded Linux operating system,implement better launch method and avoid mistakes.It also makes the program more understandable,more readable,and reduce the repeatability and coupling.It can face the new requirement better.更多还原
