IP_UNIDIRECTIONAL_ADAPTER_ADDRESS structure (ipexport.h)
The IP_UNIDIRECTIONAL_ADAPTER_ADDRESS structure stores the IPv4 addresses associated with a unidirectional adapter.
Syntax
typedef struct _IP_UNIDIRECTIONAL_ADAPTER_ADDRESS {
ULONG NumAdapters;
IPAddr Address[1];
} IP_UNIDIRECTIONAL_ADAPTER_ADDRESS, *PIP_UNIDIRECTIONAL_ADAPTER_ADDRESS;
Members
NumAdapters
The number of IPv4 addresses pointed to by the Address member.
Address[1]
An array of variables of type IPAddr. Each element of the array specifies an IPv4 address associated with this unidirectional adapter.
Remarks
The IP_UNIDIRECTIONAL_ADAPTER_ADDRESS structure is retrieved by the GetUnidirectionalAdapterInfo function. A unidirectional adapter is an adapter that can receive IPv4 datagrams, but can't transmit them.
