Functions | |
| isc_boolean_t | isc_netaddr_equal (const isc_netaddr_t *a, const isc_netaddr_t *b) |
| Compare network addresses 'a' and 'b'. Return ISC_TRUE if they are equal, ISC_FALSE if not. | |
| isc_boolean_t | isc_netaddr_eqprefix (const isc_netaddr_t *a, const isc_netaddr_t *b, unsigned int prefixlen) |
| Compare the 'prefixlen' most significant bits of the network addresses 'a' and 'b'. If 'b''s scope is zero then 'a''s scope is ignored. Return ISC_TRUE if they are equal, ISC_FALSE if not. | |
| isc_result_t | isc_netaddr_masktoprefixlen (const isc_netaddr_t *s, unsigned int *lenp) |
| Convert a netmask in 's' into a prefix length in '*lenp'. The mask should consist of zero or more '1' bits in the most most significant part of the address, followed by '0' bits. If this is not the case, ISC_R_MASKNONCONTIG is returned. | |
| isc_result_t | isc_netaddr_totext (const isc_netaddr_t *netaddr, isc_buffer_t *target) |
| Append a text representation of 'sockaddr' to the buffer 'target'. The text is NOT null terminated. Handles IPv4 and IPv6 addresses. | |
| void | isc_netaddr_format (const isc_netaddr_t *na, char *array, unsigned int size) |
| Format a human-readable representation of the network address '*na' into the character array 'array', which is of size 'size'. The resulting string is guaranteed to be null-terminated. | |
| void | isc_netaddr_fromsockaddr (isc_netaddr_t *netaddr, const isc_sockaddr_t *source) |
| void | isc_netaddr_fromin (isc_netaddr_t *netaddr, const struct in_addr *ina) |

| isc_uint32_t | isc_netaddr_getzone (const isc_netaddr_t *netaddr) |
| void | isc_netaddr_any (isc_netaddr_t *netaddr) |
| Return the IPv4 wildcard address. | |
| void | isc_netaddr_any6 (isc_netaddr_t *netaddr) |
| Return the IPv6 wildcard address. | |
| isc_boolean_t | isc_netaddr_ismulticast (isc_netaddr_t *na) |
| Returns ISC_TRUE if the address is a multicast address. | |
| isc_boolean_t | isc_netaddr_isexperimental (isc_netaddr_t *na) |
| Returns ISC_TRUE if the address is a experimental (CLASS E) address. | |
| isc_boolean_t | isc_netaddr_islinklocal (isc_netaddr_t *na) |
| Returns ISC_TRUE if the address is a link local address. | |
| isc_boolean_t | isc_netaddr_issitelocal (isc_netaddr_t *na) |
| Returns ISC_TRUE if the address is a site local address. | |
| void | isc_netaddr_fromv4mapped (isc_netaddr_t *t, const isc_netaddr_t *s) |
| Convert an IPv6 v4mapped address into an IPv4 address. | |
