WLAN_INTERFACE_INFO

.

The constructor of this structure "unmarshal" WLAN_INTERFACE_INFO_LIST data obtained by calling WlanEnumInterfaces(). This is a good example on how to marshal pointer-to-pointer case in C++ world ( kind of confusing because in C# or Managed Environment more broadly, it is just reference, so as you can see from the implementation for C#, it is to be treated like just a single pointer case. Also, this example shows how to handle an array for the InterfaceInfo inside of this structure. It needs two level of marshaling and this example shows that.
