net-snmp自定义trap怎么实现

[咔酷咿赤影]

net-snmp中，自定义trap的mib用mib2c框架生成了.c和.h文件，怎么去修改.c文件以及加触发条件，自动生成的.c如下
1 /*
2 * Note: this file originally auto-generated by mib2c using
3 * $
4 */
5
6 #include <net-snmp/net-snmp-config.h>
7 #include <net-snmp/net-snmp-includes.h>
8 #include <net-snmp/agent/net-snmp-agent-includes.h>
9 #include "DevStatetraps.h"
