## Description

SoupAddress represents the address of a TCP connection endpoint; both the IP address and the port. (It is somewhat like an object-oriented version of struct sockaddr.)

If libsoup was built with IPv6 support, SoupAddress will allow both IPv4 and IPv6 addresses.

## Details

### enum SoupAddressFamily

    typedef enum {
    	SOUP_ADDRESS_FAMILY_IPV4 = AF_INET,
    	SOUP_ADDRESS_FAMILY_IPV6 = AF_INET6
    } SoupAddressFamily;

The supported address families. Note that the `SOUP_ADDRESS_FAMILY_IPV6` constant is available even if libsoup was built without IPv6 support, but attempting to create an IPv6 address will fail in that case.

`SOUP_ADDRESS_FAMILY_IPV4` | an IPv4 address
`SOUP_ADDRESS_FAMILY_IPV6` | an IPv6 address

### SOUP_ADDRESS_ANY_PORT

    #define SOUP_ADDRESS_ANY_PORT 0

This can be passed to any SoupAddress method that expects a port to indicate that you don't care what port is used.

### soup_address_new ()

    SoupAddress* soup_address_new               (const char *name,
                                                 guint port);

Creates a SoupAddress from `name` and `port`. The SoupAddress's IP address may not be available right away; the caller can call `soup_address_resolve_async()` or `soup_address_resolve_sync()` to force a DNS resolution.

`name` : | a hostname or physical address
`port` : | a port number
Returns : | a SoupAddress

### soup_address_new_from_sockaddr ()

    SoupAddress* soup_address_new_from_sockaddr (struct sockaddr *sa,
                                                 int len);

Returns a SoupAddress equivalent to `sa` (or `NULL` if `sa`'s address family isn't supported)

`sa` : | a pointer to a sockaddr
`len` : | size of `sa`
Returns : | the new SoupAddress

### soup_address_new_any ()

    SoupAddress* soup_address_new_any           (SoupAddressFamily family,
                                                 guint port);

Returns a SoupAddress corresponding to the "any" address for `family` (or `NULL` if `family` isn't supported), suitable for passing to `soup_socket_server_new()`.

`family` : | the address family
`port` : | the port number (usually `SOUP_ADDRESS_ANY_PORT`)
Returns : | the new SoupAddress

### SoupAddressCallback ()

    void        (*SoupAddressCallback)          (SoupAddress *addr,
                                                 guint status,
                                                 gpointer data);

The callback function passed to `soup_address_resolve_async()`.

`addr` : | the SoupAddress that was resolved
`status` : | `SOUP_STATUS_OK` or `SOUP_STATUS_CANT_RESOLVE`
`data` : | the user data that was passed to `soup_address_resolve_async()`

### soup_address_resolve_async ()

    void        soup_address_resolve_async      (SoupAddress *addr,
                                                 SoupAddressCallback callback,
                                                 gpointer user_data);

Asynchronously resolves the missing half of `addr`. (Its IP address if it was created with `soup_address_new()`, or its hostname if it was created with `soup_address_new_from_sockaddr()` or `soup_address_new_any()`.) `callback` will be called when the resolution finishes (successfully or not).

`addr` : | a SoupAddress
`callback` : | callback to call with the result
`user_data` : | data for `callback`

### soup_address_resolve_sync ()

    guint       soup_address_resolve_sync       (SoupAddress *addr);

Synchronously resolves the missing half of `addr`, as with `soup_address_resolve_async()`.

`addr` : | a SoupAddress
Returns : | `SOUP_STATUS_OK` or `SOUP_STATUS_CANT_RESOLVE`

### soup_address_get_name ()

    const char* soup_address_get_name           (SoupAddress *addr);

Returns the hostname associated with `addr`.

`addr` : | a SoupAddress
Returns : | the hostname, or `NULL` if it is not known.

### soup_address_get_physical ()

    const char* soup_address_get_physical       (SoupAddress *addr);

Returns the physical address associated with `addr` as a string. (Eg, "127.0.0.1"). If the address is not yet known, returns `NULL`.

`addr` : | a SoupAddress
Returns : | the physical address, or `NULL`

### soup_address_get_port ()

    guint       soup_address_get_port           (SoupAddress *addr);

Returns the port associated with `addr`.

`addr` : | a SoupAddress
Returns : | the port
