在这以前曾经写过一篇关于函数指针数组文章，今天又看到了通信工程的应用，拷贝下来，作为参考！
1、数据结构的定义
typedef int (*IO_DETECT_FUCTION)(void);typedef struct __IO_DETECT{int id;IO_DETECT_FUCTION fun;}IO_DETECT;
2、类型实体
IO_DETECT s_IO_Detect[]={{0x01, InputPowerDetect},{0x02, InputPowerDetect1},{0x03, InputPowerDetect2},{0x04, InputPowerDetect3},{0x05, DownBrokenDectect},{0x06, UpBrokenDetect},{0x07, UpBrokenDetect1},{0x08, OpticalTransDetect},{0x09, UpOutputDetect},{0x0A, SlaveDCAlarm},{0x0B, SlaveACAlarm},{0x0C, SolarEnergyDetect},{0x0D, MainInputPowerDetect1},{0x0E, MainInputPowerDetect2},{0x0F, BackupInputPowerDetect1},{0x10, BackupInputPowerDetect2},{0x11, GZDTInputPowerDetect},{0x12, GZDTOpeicalAlarmDect},{0x13, BJDTSlaveDCAlarm},{0x14, BJDTUpOutputDetect},{0x15, BJDTSlaveACAlarm},{0x16, DCAlarm},{0x17, ACAlarm},{0x18, GSMCTDownInputPowerDetect},{0x19, CMMBInputPowerDetect},{0x1A, BeiJingInputPowerDetect},{0x1B, BeiJingOutputPowerDetect},{0x1C, CDMAInputPowerDetect1},{0x1D, DCAlarm1V},{0x1E, ACAlarm1V},{0x1F, BAT13VDect},{0x20, BAT48VDect},{0x21, ReportKey},{0x22, InputPowerDetect4},{0x23, OutputPowerDetect1},{0x24, RePowerDetect1},{0x25, ACLow_Alarm}};
3、函数调用
int IO_DetectFunction(int Id){int i = 0;int ret = 0;for(i=0; i < sizeof(s_IO_Detect)/sizeof(IO_DETECT); i++){if( s_IO_Detect[i].id == Id ){ret = s_IO_Detect[i].fun();break;}}return ret;}
，人只要不失去方向，就不会失去自己
