Function Documentation

addr_to_normalized_string()

std::string net::addr_to_normalized_string

(

boost::asio::ip::address

address

)

Get the given address in normalized string form.

Normalization converts IPv4-mapped IPv6 addresses into IPv4 addresses.

Parameters

address

The address to normalize.

Returns

Normalized address in string form.

addr_to_url_escaped_string()

std::string net::addr_to_url_escaped_string

(

boost::asio::ip::address

address

)

Get the given address in a normalized form for the host portion of a URL.

Normalization converts IPv4-mapped IPv6 addresses into IPv4 addresses.

Parameters

address

The address to normalize and escape.

Returns

Normalized address in URL-escaped string.

af_from_enum_string()

af_e net::af_from_enum_string

(

const std::string_view &

view

)

Get the address family enum value from a string.

Parameters

view	The config option value.

Returns

The address family enum value.

af_to_any_address_string()

std::string_view net::af_to_any_address_string

(

af_e

af

)

Get the wildcard binding address for a given address family.

Parameters

af	Address family.

Returns

Normalized address.

encryption_mode_for_address()

int net::encryption_mode_for_address

(

boost::asio::ip::address

address

)

Get the encryption mode for the given remote endpoint address.

Parameters

address

The address used to look up the desired encryption mode.

Returns

The WAN or LAN encryption mode, based on the provided address.

map_port()

std::uint16_t net::map_port

(

int

port

)

Map a specified port based on the base port.

Parameters

port	The port to map as a difference from the base port.

Returns

The mapped port number.

Examples

std::uint16_t mapped_port = net::map_port(1);

Todo

Ensure port is not already in use by another application.

mdns_instance_name()

std::string net::mdns_instance_name

(

const std::string_view &

hostname

)

Returns a string for use as the instance name for mDNS.

Parameters

hostname

The hostname to use for instance name generation.

Returns

Hostname-based instance name or "Sunshine" if hostname is invalid.

normalize_address()

boost::asio::ip::address net::normalize_address

(

boost::asio::ip::address

address

)

Convert an address to a normalized form.

Normalization converts IPv4-mapped IPv6 addresses into IPv4 addresses.

Parameters

address

The address to normalize.

Returns

Normalized address.
