get_interface_metric()

int get_interface_metric	(	const NET_IFINDEX	index,
		const ADDRESS_FAMILY	family,
		int *	is_auto )

Return interface metric value for the specified interface index.

Parameters

index	The index of TAP adapter.
family	Address family (AF_INET for IPv4 and AF_INET6 for IPv6).
is_auto	On return set to true if automatic metric is in use. Unused if NULL.

Returns

positive interface metric on success or -1 on error

set_interface_metric()

DWORD set_interface_metric	(	const NET_IFINDEX	index,
		const ADDRESS_FAMILY	family,
		const ULONG	metric )

Sets interface metric value for specified interface index.

Parameters

index	The index of TAP adapter
family	Address family (AF_INET for IPv4 and AF_INET6 for IPv6)
metric	Metric value. 0 for automatic metric

Returns

0 on success, a non-zero status code of the last failed action on failure.
