| 摘 要： | 在Unix下,目前有两种主流共享内存机制,一种是Posix共享内存机制,另一种是System V共享内存机制.本文阐述了这两种共享内存机制的实际实现方法,比较了他们之间的特点与不同.并结合在铁路电力监控系统中的应用,阐述了Posix共享内存机制是如何实现监控系统中的自适应共享内存机制的.

| Abstract: | There are two kinds of main current share memory mechanisms currently under the Unix,a kind is the Posix share memory mechanism,another kind is the System V share memory mechanism.This text elaborated these two kinds of share memory mechanism and their actural realization method,conapated their characteristics and dissimilarity.Combining also the application in the railroad electric power supervise and control system,the paper explains how the Posix share memory mechanism implement the adaptive share memory mechanism in the supervision system. |
