函数

DWORD GetIfTable(
PMIB_IFTABLE pIfTable,
PULONG pdwSize,
BOOL bOrder
);

功能

获取MIB-II接口列表

参数

PMIB_IFTABLE pIfTable：接收缓冲区，接收GetIfTable返回的MIB-II接口表

PULONG pdwSize：pIfTable缓冲区字节数，若缓冲区过小则返回所需大小

BOOL bOrder：指定pIfTable中返回的接口列表条目是否根据接口索引排序

细说MIB_IFROW结构体成员

dwType：接口类型，例如IF_TYPE_ETHERNET_CSMACD=6, Ethernet网络接口；IF_TYPE_SOFTWARE_LOOPBACK=24，软件回环测试网络接口。23号之前的网络接口可用来统计系统流量。

dwSpeed：接口速度，单位bps，可用来计算网络带宽

bPhysAddr：接口网卡的MAC地址

dwInOctets：接收的字节数，自系统启动，可用来统计系统网络流量。
dwOutOctets：发送的字节数，自系统启动，可用来统计系统网络流量。

网卡的传输速度有10Mbps、100Mbps、1000Mbps，查看网卡速度的方法：设备管理器—网络适配器—选择网卡—属性—高级—连接速度和双工模式—值—下拉菜单中的最大值。

网络带宽由多种因素决定，例如为连接在只具备100M传输速度的双绞线上的计算机配置1000M的网卡就是一种浪费，因为其至多也只能实现100M的传输速率。

故网络带宽为各种物理介质中的最小值，可认为是所有网卡传输速度的最小值（且不为0）。
