nldef.h contains the following programming interfaces:

Structures

NL_BANDWIDTH_INFORMATION Contains read-only information on the available bandwidth estimates and associated variance as determined by the TCP/IP stack.
NL_INTERFACE_OFFLOAD_ROD Specifies a set of flags that indicate the offload capabilities for an IP interface.
NL_NETWORK_CONNECTIVITY_HINT Describes a level of network connectivity, the usage charge for a network connection, and other members reflecting cost factors.

Enumerations

NL_ADDRESS_TYPE The NL_ADDRESS_TYPE enumeration type specifies the IP address type of the network layer.
NL_DAD_STATE The IP_DAD_STATE enumeration specifies information about the duplicate address detection (DAD) state for an IPv4 or IPv6 address.
NL_LINK_LOCAL_ADDRESS_BEHAVIOR The NL_LINK_LOCAL_ADDRESS_BEHAVIOR enumeration type defines the link local address behavior.
NL_NEIGHBOR_STATE The NL_NEIGHBOR_STATE enumeration type defines the state of a network layer neighbor IP address, as described in RFC 2461, section 7.3.2.
NL_NETWORK_CONNECTIVITY_COST_HINT Defines constants that specify hints about the usage charge for a network connection.
NL_NETWORK_CONNECTIVITY_LEVEL_HINT Defines constants that specify hints about a level of network connectivity.
NL_PREFIX_ORIGIN The IP_PREFIX_ORIGIN enumeration specifies the origin of an IPv4 or IPv6 address prefix, and is used with the IP_ADAPTER_UNICAST_ADDRESS structure.
NL_ROUTE_ORIGIN The NL_ROUTE_ORIGIN enumeration type defines the origin of the IP route.
NL_ROUTE_PROTOCOL The NL_ROUTE_PROTOCOL enumeration type defines the routing mechanism that an IP route was added with, as described in RFC 4292.
NL_ROUTER_DISCOVERY_BEHAVIOR The NL_ROUTER_DISCOVERY_BEHAVIOR enumeration type defines the router discovery behavior, as described in RFC 2461.
NL_SUFFIX_ORIGIN The IP_SUFFIX_ORIGIN enumeration specifies the origin of an IPv4 or IPv6 address suffix, and is used with the IP_ADAPTER_UNICAST_ADDRESS structure.
