結構體介紹
The FIXED_INFO structure contains information that is the same across all the interfaces on a computer.
FIXED_INFO結構體包含
#include Iphlpapi.h.
定義
typedef struct {
char HostName[MAX_HOSTNAME_LEN + 4];//本地計算機的主機名稱
char DomainName[MAX_DOMAIN_NAME_LEN + 4];//本地計算機已註冊的域名
PIP_ADDR_STRING CurrentDnsServer;//使用DnsServerList為本地計算機獲取DNS服務
IP_ADDR_STRING DnsServerList;//一個本地計算機可用的DNS伺服器的IP_ADDR_STRING結構體鍊表
UINT NodeType;//本地計算機節點類型
char ScopeId[MAX_SCOPE_ID_LEN + 4];//DHCP範圍內的名字
UINT EnableRouting;//指定本地計算機路由功能是否開啟
UINT EnableProxy;//指定本地計算機是否作為ARP代理
UINT EnableDns;//指定本地計算機DNS是否開啟
} FIXED_INFO, *PFIXED_INFO;
使用
The FIXED_INFO structure is retrieved by the GetNetworkParams function.
