MIB_UNICASTIPADDRESS_TABLE 結構 (netioapi.h)
MIB_UNICASTIPADDRESS_TABLE 結構包含單播IP位址項目的數據表。
語法
typedef struct _MIB_UNICASTIPADDRESS_TABLE {
ULONG NumEntries;
MIB_UNICASTIPADDRESS_ROW Table[ANY_SIZE];
} MIB_UNICASTIPADDRESS_TABLE, *PMIB_UNICASTIPADDRESS_TABLE;
成員
NumEntries
值，指定陣列中的單播IP位址項目數目。
Table[ANY_SIZE]
包含單播IP位址專案的 MIB_UNICASTIPADDRESS_ROW 結構的陣列。
備註
MIB_UNICASTIPADDRESS_TABLE 結構是在 Windows Vista 和更新版本上定義。
GetUnicastIpAddressTable 函式會列舉本機系統上的單播 IP 位址，並在MIB_UNICASTIPADDRESS_TABLE結構中傳回這項資訊。
MIB_UNICASTIPADDRESS_TABLE 結構可能包含 NumEntries 成員與 Table 成員中第一個MIB_UNICASTIPADDRESS_ROW陣列專案之間的對齊填補。 表格成員中的MIB_UNICASTIPADDRESS_ROW數位專案之間也可能有對齊的填補。 任何對 MIB_UNICASTIPADDRESS_ROW 陣列專案的存取都應該假設可能存在填補。
範例
下列範例會擷取單播IP位址表，並列印每個擷取 MIB_UNICASTIPADDRESS_ROW 結構中的一些值。
