| 109 | * |
| 110 | * Gather the network interfaces and the addresses corresponding to them, |
| 111 | * check if they match to the search criteria specifed by @a hints and |
| 112 | * return a list of matching local address information in the @a |
| 113 | * return_localinfo. The local address information may include IPv4/IPv6 |
| 114 | * addresses, interface name, interface index, address scope, and domain |
| 115 | * names corresponding to the local addresses. |
| 116 | * |
| 117 | * @param[in] hints specifies selection criteria |
| 118 | * @param[out] return_localinfo return list of local addresses |
| 119 | * |
| 120 | * @par Selection criteria - hints |
| 121 | * |
| 122 | * The selection criteria @a hints is used to select which addresses are |
| 123 | * returned and what kind of information is included in the @a res list. |
| 124 | * |
| 125 | * @par Selection by flags - hints->li_flags |
| 126 | * |
| 127 | * The @a hints->li_flags contain flags, which can be combined with bit-wise |
| 128 | * or. The currently defined flags are as follows: |
| 129 | * |
| 130 | * - #LI_V4MAPPED: when returning IPv4 addresses, map them as IPv6 |
| 131 | * addresses. If this flag is specified, IPv4 addresses are returned even |
| 132 | * if @a hints->li_family is set to @c AF_INET6. |
| 133 | * - #LI_CANONNAME: return the domain name (DNS PTR) corresponding to the |
| 134 | * local address in @a li_canonname. |
| 135 | * - #LI_NAMEREQD: Do not return addresses not in DNS. |
| 136 | * - #LI_NUMERIC: instead of domain name, return the text presentation of |
| 137 | * the addresss in @a li_canonname. |
| 138 | * - #LI_DOWN: include interfaces and their addresses even if the interfaces |
| 139 | * are down. New in @VERSION_1_12_2. |
| 140 | * - #LI_IFNAME: return the interface name in @a li_ifname. |
| 141 | * |
| 142 | * @par Selection by address family - hints->li_family |
| 143 | * |
| 144 | * The address family can have three values: 0, AF_INET and AF_INET6. If |
| 145 | * address family @a hints->li_family, both IPv4 and IPv6 addresses are |
| 146 | * returned. |
| 147 | * |
| 148 | * @par Selection by interface index - hints->li_index |
| 149 | * |
| 150 | * If the field @a hints->li_index is non-zero, only the addresses assigned |
| 151 | * to the interface with given index are returned. The list of interface |
| 152 | * indices and names can be obtained by the function @c su_if_names(). |
| 153 | * |
| 154 | * @par Selection by interface name - hints->li_ifname |
| 155 | * |
| 156 | * If the field @a hints->li_ifname is not NULL, only the addresses assigned |
| 157 | * to the named interface are returned. The list of interface names can be |
| 158 | * obtained by the function @c su_if_names(). |
| 159 | * |
| 160 | * @par Selection by address scope - hints->li_scope |
| 161 | * |
| 162 | * If the field @a hints->li_scope is nonzero, only the addresses with |
| 163 | * matching scope are returned. The different address scopes can be combined |
| 164 | * with bitwise or. They are defined as follows |
| 165 | * - #LI_SCOPE_HOST: host-local address, valid within host (::1, 127.0.0.1/8) |
| 166 | * - #LI_SCOPE_LINK: link-local address, valid within link |
| 167 | * (IP6 addresses with prefix fe80::/10, |
| 168 | * IP4 addresses in net 169.254.0.0/16). |
| 169 | * - #LI_SCOPE_SITE: site-local address, addresses valid within organization |
| 170 | * (IPv6 addresses with prefix fec::/10, |
| 171 | * private IPv4 addresses in nets 10.0.0.0/8, 172.16.0.0/12, |
| 172 | * and 192.168.0.0/16 as defined in @RFC1918) |
| 173 | * - #LI_SCOPE_GLOBAL: global address. |
| 174 | * |
| 175 | * For instance, setting @a hints->li_scope to @c LI_SCOPE_GLOBAL | @c |
| 176 | * LI_SCOPE_SITE, both the @e global and @e site-local addresses are |
| 177 | * returned. |
| 178 | * |
| 179 | * @sa @RFC1918, @RFC4291, su_sockaddr_scope() |
| 180 | * |
| 181 | * @par Selection by domain name - hints->li_canonname |
| 182 | * |
| 183 | * If this field is non-null, the domain name (DNS PTR) corresponding to |
| 184 | * local IP addresses should match to the name given in this field. |
| 185 | * |
| 186 | * @return Zero (#ELI_NOERROR) when successful, or negative error code when |
| 187 | * failed. |
| 188 | * |
| 189 | * @par Diagnostics |
| 190 | * Use su_gli_strerror() in order to obtain a string describing the error |
| 191 | * code returned by su_getlocalinfo(). |
