IpAddr ( const uint8_t * v6_data )

inlineexplicitnoexcept

Construct an IPv6 address from its raw 16-byte array representation.

Parameters

[in] v6_data Pointer to the address data, an array of length ETCPAL_IPV6_BYTES.

IpAddr	(	const uint8_t *	v6_data,
		unsigned long	scope_id
	)

inlinenoexcept

Member Function Documentation

◆ FromString() [1/2]

IpAddr FromString ( const char * ip_str )

inlinestaticnoexcept

Construct an IpAddr from a string representation.

See etcpal_string_to_ip() for more information.

◆ FromString() [2/2]

IpAddr FromString ( const std::string & ip_str )

inlinestaticnoexcept

Construct an IpAddr from a string representation.

See etcpal_string_to_ip() for more information.

◆ IsWildcard()

bool IsWildcard ( ) const

inlinenoexcept

Whether an IpAddr contains a wildcard address.

See etcpal_ip_is_wildcard() for more information.

◆ MaskLength()

unsigned int MaskLength ( ) const

inlinenoexcept

The number of consecutive set bits in a netmask.

See etcpal_ip_mask_length() for more information.

◆ Netmask()

IpAddr Netmask	(	IpAddrType	type,
		unsigned int	mask_length
	)

inlinestaticnoexcept

◆ scope_id()

constexpr unsigned long scope_id ( ) const

constexprnoexcept

Get the scope ID of an IPv6 address.

Scope IDs (sometimes referred to as Zone IDs or Zone Indices) are a lightly-documented portion of IPv6 addressing, but one concrete use is to indicate the network interface index of a link-local IPv6 address. See also Network Interface Indexes.

This function will return undefined data if the IpAddr's type is V4 or Invalid.

Returns: The scope ID.

◆ SetAddress() [1/3]

void SetAddress ( const uint8_t * v6_data )

inlinenoexcept

Set the IPv6 address data.

Automatically converts this address's type to V6.

Parameters

[in] v6_data Pointer to the address data, an array of length ETCPAL_IPV6_BYTES.

◆ SetAddress() [2/3]

void SetAddress	(	const uint8_t *	v6_data,
		unsigned long	scope_id
	)

inlinenoexcept

Set the IPv6 address data and scope ID.

See scope_id() for more information.

Parameters

[in]	v6_data	Pointer to the address data, an array of length ETCPAL_IPV6_BYTES.
[in]	scope_id	The address's scope ID.

◆ SetAddress() [3/3]

void SetAddress ( uint32_t v4_data )

inlinenoexcept

Set the IPv4 address data.

Automatically converts this address's type to V4.

Parameters

[in] v4_data The address data in host byte order.

◆ ToString()

std::string ToString ( ) const

inline

Convert the IP address to a string representation.

See etcpal_ip_to_string() for more information.

◆ ToV6Array()

std::array< uint8_t, ETCPAL_IPV6_BYTES > ToV6Array ( ) const

inline

Get a 16-byte std::array representation of an IPv6 address.

Copies the data into a new array. This function will return undefined data if the IpAddr's type is V4 or Invalid.

◆ v4_data()

constexpr uint32_t v4_data ( ) const

constexprnoexcept

Get the raw 32-bit representation of an IPv4 address.

This function will return undefined data if the IpAddr's type is V6 or Invalid.

Returns: The address data in host byte order.

◆ v6_data()

constexpr const uint8_t * v6_data ( ) const

constexprnoexcept

Get the raw 16-byte array representation of an IPv6 address.

The returned pointer has the same lifetime as this IpAddr instance. This function will return undefined data if the IpAddr's type is V4 or Invalid.

◆ Wildcard()

IpAddr Wildcard ( IpAddrType type )

inlinestaticnoexcept

Construct a wildcard address of the type specified.

See etcpal_ip_set_wildcard() for more information.

◆ WildcardV4()

IpAddr WildcardV4 ( )

inlinestaticnoexcept

Construct a wildcard IPv4 address.

See etcpal_ip_set_wildcard() for more information.

◆ WildcardV6()

IpAddr WildcardV6 ( )

inlinestaticnoexcept
