Function Documentation

◆ tor_inet_aton()

int tor_inet_aton	(	const char *	str,
		struct in_addr *	addr
	)

Set *addr to the IP address (in dotted-quad notation) stored in *str. Return 1 on success, 0 if *str is badly formatted. (Like inet_aton(str,addr), but works on Windows and Solaris.)

◆ tor_inet_ntoa()

int tor_inet_ntoa	(	const struct in_addr *	in,
		char *	buf,
		size_t	buf_len
	)

Given an IPv4 in_addr struct *in (in network order, as usual), write it as a string into the buf_len-byte buffer in buf. Returns a non-negative integer on success. Returns -1 on failure.

◆ tor_inet_ntop()

const char* tor_inet_ntop	(	int	af,
		const void *	src,
		char *	dst,
		size_t	len
	)

Given af==AF_INET and src a struct in_addr, or af==AF_INET6 and src a struct in6_addr, try to format the address and store it in the len-byte buffer dst. Returns dst on success, NULL on failure.

(Like inet_ntop(af,src,dst,len), but works on platforms that don't have it: Tor sometimes needs to format ipv6 addresses even on platforms without ipv6 support.)

◆ tor_inet_pton()

int tor_inet_pton	(	int	af,
		const char *	src,
		void *	dst
	)

Given af==AF_INET or af==AF_INET6, and a string src encoding an IPv4 address or IPv6 address correspondingly, try to parse the address and store the result in dst (which must have space for a struct in_addr or a struct in6_addr, as appropriate). Return 1 on success, 0 on a bad parse, and -1 on a bad af.

(Like inet_pton(af,src,dst) but works on platforms that don't have it: Tor sometimes needs to format ipv6 addresses even on platforms without ipv6 support.)
