Data Structures
union	ipv4_addr_t
	Data type to represent an IPv4 address. More...

Macros
#define	IPV4_ADDR_MAX_STR_LEN (sizeof("255.255.255.255"))
	Maximum length of an IPv4 address as string.

#define	IPV4_ADDR_INIT(a, b, c, d) { .u8 = {a, b, c, d} }
	Static initializer for an IPv4 address.

Functions
static bool	ipv4_addr_equal (const ipv4_addr_t a, const ipv4_addr_t b)
	Checks if two IPv4 addresses are equal.

static bool	ipv4_addr_is_multicast (const ipv4_addr_t *addr)
	Check if `addr` is a multicast address.

char *	ipv4_addr_to_str (char result, const ipv4_addr_t addr, uint8_t result_len)
	Converts an IPv4 address to its string representation.

ipv4_addr_t *	ipv4_addr_from_str (ipv4_addr_t result, const char addr)
	Converts an IPv4 address string representation to a byte-represented IPv4 address.

ipv4_addr_t *	ipv4_addr_from_buf (ipv4_addr_t result, const char addr, size_t addr_len)
	Converts an IPv4 address from a buffer of characters to a byte-represented IPv4 address.

void	ipv4_addr_print (const ipv4_addr_t *addr)
	Print IPv4 address to stdout.
