Detailed Description

Parameters

[in]	a	lrtr_ip_addr
[in]	b	lrtr_ip_addr

Returns

true If a == b.

false If a != b.

Function Documentation

int lrtr_ip_addr_to_str	(	const struct lrtr_ip_addr *	ip,
		char *	str,
		const unsigned int	len
	)

Converts the passed lrtr_ip_addr struct to string representation.

Parameters

[in]	ip	lrtr_ip_addr
[out]	str	Pointer to a char array. The array must be at least INET_ADDRSTRLEN bytes long if the passed lrtr_ip_addr stores an IPv4 address. If lrtr_ip_addr stores an IPv6 address, str must be at least INET6_ADDRSTRLEN bytes long.
[in]	len	Length of the str array.

Returns

0 On success.

-1 On error.

bool lrtr_ip_str_cmp	(	const struct lrtr_ip_addr *	addr1,
		const char *	addr2
	)

Compares addr1 in the lrtr_ip_addr struct with addr2 in string representation.

Parameters

[in]	addr1	lrtr_ip_addr
[in]	addr2	IP-address as string

Returns

true If a == b

false If a != b

int lrtr_ip_str_to_addr	(	const char *	str,
		struct lrtr_ip_addr *	ip
	)

Converts the passed IP address in string representation to an lrtr_ip_addr.

Parameters

[in]	str	Pointer to a Null terminated char array.
[out]	ip	Pointer to a lrtr_ip_addr struct.

Returns

0 On success.

-1 On error.

void lrtr_ipv4_addr_convert_byte_order	(	const uint32_t	src,
		uint32_t *	dest,
		const enum target_byte_order	tbo
	)

Converts the passed IPv4 address to given byte order.

[{

Parameters

[in]	src	IPv4 address in source byte order.
[out]	dest	IPv4 address in target byte order.
[in]	tbo	Target byte order for address conversion. }

void lrtr_ipv6_addr_convert_byte_order	(	const uint32_t *	src,
		uint32_t *	dest,
		const enum target_byte_order	tbo
	)

Converts the passed IPv6 address to given byte order.

Parameters

[in]	src	IPv6 address (uint32_t array) in source byte order.
[out]	dest	IPv6 address (uint32_t array) in target byte order.
[in]	tbo	Target byte order for address conversion.
