The IP_UNIDIRECTIONAL_ADAPTER_ADDRESS structure contains the number of unidirectional adapters on the local computer, and the IP addresses that are associated with those adapters.
typedef struct _IP_UNIDIRECTIONAL_ADAPTER_ADDRESS {
  ULONG NumAdapters;
  IPAddr Address[1];
} IP_UNIDIRECTIONAL_ADAPTER_ADDRESS, *PIP_UNIDIRECTIONAL_ADAPTER_ADDRESS;
For information about the IPAddr data type, see Win32 Simple Data Types. To convert an IP address between dotted decimal notation and IPAddr format, use the inet_addr and inet_ntoa functions.
