管理信息库（MIB）定义了由代理者维护的各种变量，它们由管理者来进行存取操作，从而实现具体的网络管理。本文在对MIB的分析之后，给出了对MIB库变量访问的C语言程序实例.-Management Information Base (MIB) is defined by the agent to maintain a variety of variables, their access by managers to carry out operations, in order to achieve a specific network management. In this paper, the analysis of the MIB are given access to the MIB database variables examples of the C language program.
