get_link_local_address()

struct sockaddr_in6 wx::ipv6::get_link_local_address

(

const char *

interface_name

)

Gets the first link-local address for the specified network interface.

Note that it is possible for an interface to have more than one link-local address. In this case, one is selected at random (and subsequent calls may not return the same address). It is also possible for an interface to have no link-local address (for example, if IPv6 is disabled).

Parameters

interface_name

The name of the network interface.

Returns

The IPv6 link-local address.

Exceptions

std::system_error	An error occurred.
std::runtime_error	The specified interface doesn't exist or has no link-local address.

is_link_local()

bool wx::ipv6::is_link_local ( const in6_addr &  address )

noexcept

Tests if an IPv6 address has link-local scope.

An address has link-local scope if and only if it is in the range [fe80::, fe81::).

Parameters

address

The IPv6 address to test.

Returns

true if address has link-local scope.

to_string()

std::string wx::ipv6::to_string

(

const in6_addr &

address

)

Produces a string representation of an IPv6 address.

Parameters

address

The IPv6 address to convert.

Returns

A string representation of address, using :: shorthand notation where possible.
