Function Documentation

int hg_get_name_from_ip	(	struct in6_addr *	ip,
		char *	hostname,
		int	sz
	)

Parameters

[out]	hostname	Pointer to buffer that will contain hostname if successful.
[in]	sz	Size of hostname buffer hostname.

Returns

Always returns 0.

void hg_host_cleanup

(

struct hg_host *

hosts)

void hg_hosts_cleanup

(

struct hg_host *

hosts)

Frees all hosts that are linked in hosts, using hg_host_cleanup.

Parameters

hosts

host list to free.

char* hg_name_to_domain

(

char *

hostname)

input : hostname (ie : www.if.arf.com) returns: if.arf.com

If the input is arf.com returns : NULL

int hg_resolv	(	char *	hostname,
		struct in6_addr *	in6addr,
		int	family
	)

Resolve an hostname.

Todo:

getaddrinfo: host might resolve to more than one ip. In this case (ai->ai_next != NULL). This should somehow be respected, probably needs changes to interface.

int hg_valid_ip_addr

(

char *

hostname)

Returns

0 if adress info for hostname could be found, 1 otherwise.
