结构体介绍

The FIXED_INFO structure contains information that is the same across all the interfaces on a computer.

FIXED_INFO结构体包含

头文件

#include Iphlpapi.h.

定义

typedef struct {

char HostName[MAX_HOSTNAME_LEN + 4];//本地计算机的主机名称

char DomainName[MAX_DOMAIN_NAME_LEN + 4];//本地计算机已注册的域名

PIP_ADDR_STRING CurrentDnsServer;//使用DnsServerList为本地计算机获取DNS服务

IP_ADDR_STRING DnsServerList;//一个本地计算机可用的DNS服务器的IP_ADDR_STRING结构体链表

UINT NodeType;//本地计算机节点类型

char ScopeId[MAX_SCOPE_ID_LEN + 4];//DHCP范围内的名字

UINT EnableRouting;//指定本地计算机路由功能是否开启

UINT EnableProxy;//指定本地计算机是否作为ARP代理

UINT EnableDns;//指定本地计算机DNS是否开启

} FIXED_INFO, *PFIXED_INFO;

使用

The FIXED_INFO structure is retrieved by the GetNetworkParams function.
