The index of the current item. The index of the first item is 0. The dwIndex member must be less than the dwNumberOfItems member. This member is not used by the wireless service. Applications can use this member when processing individual profiles in the WLAN_PROFILE_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.
