        ╰── SoupAddress

## Implemented Interfaces

SoupAddress implements GSocketConnectable.

## Includes

    #include <libsoup/soup.h>

## 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.)

Although SoupAddress is still used in some libsoup API's, it should not be used in new code; use GLib's GNetworkAddress or GSocketAddress instead.

## Functions

### 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.

#### Parameters

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)

#### Parameters

sa | a pointer to a sockaddr |
len | size of `sa` |

#### Returns

the new SoupAddress.

[nullable]

### 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 using as a listening SoupSocket.

#### Parameters

family | the address family |
port | the port number (usually `SOUP_ADDRESS_ANY_PORT`) |

#### Returns

the new SoupAddress.

[nullable]

### SoupAddressCallback ()

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

The callback function passed to `soup_address_resolve_async()`.

#### Parameters

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

### soup_address_resolve_async ()

    void
    soup_address_resolve_async (SoupAddress *addr,
                                GMainContext *async_context,
                                GCancellable *cancellable,
                                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()`.)

If `cancellable` is non-`NULL`, it can be used to cancel the resolution. `callback` will still be invoked in this case, with a status of `SOUP_STATUS_CANCELLED`.

It is safe to call this more than once on a given address, from the same thread, with the same `async_context` (and doing so will not result in redundant DNS queries being made). But it is not safe to call from multiple threads, or with different `async_contexts` , or mixed with calls to `soup_address_resolve_sync()`.

#### Parameters

addr | a SoupAddress |
async_context | the GMainContext to call `callback` from. | [allow-none]
cancellable | a GCancellable object, or `NULL` |
callback | callback to call with the result. | [scope async]
user_data | data for `callback` |

### soup_address_resolve_sync ()

    guint
    soup_address_resolve_sync (SoupAddress *addr,
                               GCancellable *cancellable);

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

If `cancellable` is non-`NULL`, it can be used to cancel the resolution. `soup_address_resolve_sync()` will then return a status of `SOUP_STATUS_CANCELLED`.

It is safe to call this more than once, even from different threads, but it is not safe to mix calls to `soup_address_resolve_sync()` with calls to `soup_address_resolve_async()` on the same address.

#### Parameters

addr | a SoupAddress |
cancellable | a GCancellable object, or `NULL` |

#### Returns

`SOUP_STATUS_OK`, `SOUP_STATUS_CANT_RESOLVE`, or `SOUP_STATUS_CANCELLED`.

### soup_address_is_resolved ()

    gboolean
    soup_address_is_resolved (SoupAddress *addr);

Tests if `addr` has already been resolved. Unlike the other SoupAddress "get" methods, this is safe to call when `addr` might be being resolved in another thread.

#### Parameters

addr | a SoupAddress |

#### Returns

`TRUE` if `addr` has been resolved.

### soup_address_get_name ()

    const char *
    soup_address_get_name (SoupAddress *addr);

Returns the hostname associated with `addr` .

This method is not thread-safe; if you call it while `addr` is being resolved in another thread, it may return garbage. You can use `soup_address_is_resolved()` to safely test whether or not an address is resolved before fetching its name or address.

#### Parameters

addr | a SoupAddress |

#### Returns

the hostname, or `NULL` if it is not known.

[nullable]

### soup_address_get_sockaddr ()

    struct sockaddr *
    soup_address_get_sockaddr (SoupAddress *addr,
                               int *len);

Returns the sockaddr associated with `addr` , with its length in *`len` . If the sockaddr is not yet known, returns `NULL`.

This method is not thread-safe; if you call it while `addr` is being resolved in another thread, it may return garbage. You can use `soup_address_is_resolved()` to safely test whether or not an address is resolved before fetching its name or address.

#### Parameters

addr | a SoupAddress |
len | return location for sockaddr length |

#### Returns

the sockaddr, or `NULL`.

[nullable][transfer none]

### soup_address_get_gsockaddr ()

    GSocketAddress *
    soup_address_get_gsockaddr (SoupAddress *addr);

Creates a new GSocketAddress corresponding to `addr` (which is assumed to only have one socket address associated with it).

#### Parameters

addr | a SoupAddress |

#### Returns

a new GSocketAddress.

[transfer full]

Since 2.32

### 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`.

This method is not thread-safe; if you call it while `addr` is being resolved in another thread, it may return garbage. You can use `soup_address_is_resolved()` to safely test whether or not an address is resolved before fetching its name or address.

#### Parameters

addr | a SoupAddress |

#### Returns

the physical address, or `NULL`.

[nullable]

### soup_address_get_port ()

    guint
    soup_address_get_port (SoupAddress *addr);

Returns the port associated with `addr` .

#### Parameters

addr | a SoupAddress |

#### Returns

the port

### soup_address_equal_by_name ()

    gboolean
    soup_address_equal_by_name (gconstpointer addr1,
                                gconstpointer addr2);

Tests if `addr1` and `addr2` have the same "name". This method can be used with `soup_address_hash_by_name()` to create a GHashTable that hashes on address "names".

Comparing by name normally means comparing the addresses by their hostnames. But if the address was originally created using an IP address literal, then it will be compared by that instead.

In particular, if "www.example.com" has the IP address 10.0.0.1, and `addr1` was created with the name "www.example.com" and `addr2` was created with the name "10.0.0.1", then they will compare as unequal for purposes of `soup_address_equal_by_name()`.

This would be used to distinguish hosts in situations where different virtual hosts on the same IP address should be considered different. Eg, for purposes of HTTP authentication or cookies, two hosts with the same IP address but different names are considered to be different hosts.

See also `soup_address_equal_by_ip()`, which compares by IP address rather than by name.

#### Parameters

addr1 | a SoupAddress with a resolved name. | [type Soup.Address]
addr2 | another SoupAddress with a resolved name. | [type Soup.Address]

#### Returns

whether or not `addr1` and `addr2` have the same name

Since 2.26

### soup_address_hash_by_name ()

    guint
    soup_address_hash_by_name (gconstpointer addr);

A hash function (for GHashTable) that corresponds to `soup_address_equal_by_name()`, qv

#### Parameters

addr | a SoupAddress. | [type Soup.Address]

#### Returns

the named-based hash value for `addr` .

Since 2.26

### soup_address_equal_by_ip ()

    gboolean
    soup_address_equal_by_ip (gconstpointer addr1,
                              gconstpointer addr2);

Tests if `addr1` and `addr2` have the same IP address. This method can be used with `soup_address_hash_by_ip()` to create a GHashTable that hashes on IP address.

This would be used to distinguish hosts in situations where different virtual hosts on the same IP address should be considered the same. Eg, if "www.example.com" and "www.example.net" have the same IP address, then a single connection can be used to talk to either of them.

See also `soup_address_equal_by_name()`, which compares by name rather than by IP address.

#### Parameters

addr1 | a SoupAddress with a resolved IP address. | [type Soup.Address]
addr2 | another SoupAddress with a resolved IP address. | [type Soup.Address]

#### Returns

whether or not `addr1` and `addr2` have the same IP address.

Since 2.26

### soup_address_hash_by_ip ()

    guint
    soup_address_hash_by_ip (gconstpointer addr);

A hash function (for GHashTable) that corresponds to `soup_address_equal_by_ip()`, qv

#### Parameters

addr | a SoupAddress. | [type Soup.Address]

#### Returns

the IP-based hash value for `addr` .

Since 2.26
