The index of the current item. The index of the first item is 0. dwIndex must be less than dwNumberOfItems. This member is not used by the wireless service. Applications can use this member when processing individual interfaces in the WLAN_INTERFACE_INFO_LIST structure. When an application passes this structure from one function to another, it can set the value of dwIndex to the index of the item currently being processed. This can help an application maintain state. dwIndex should always be initialized before use.
