基于SCO Unix Ware的实时消息队列设计与实现

Design and Implement of Real-Time Message Queue Baded on SCO UnixWare

实时消息队列作为一种IPC是在POSIX.1中定义的.但SCOUnixWare的最新版本7.1.3并不支持.结合实际开发的需要,提出了一种基于存储映射I/O和SystemV消息队列在用户级实现实时消息队列的方法,并在SCOUnixWare7.1.3上实现.结果表明,该方法是非常有效的,它能够在用户级提供一种高效的进程间实时通信机制.

As a kind of IPC, real-time message queue is defined in POSIX.1. However, the latest version of SCO UnixWare 7.1.3 doesn't support it. Authors gives a new way to implement it in user level based on memory mapped I/O and system V message queue. Result proves that it can provide an efficient real-time inter-process communication mechanism.
