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_async_full ()

void                soup_address_resolve_async_full     (SoupAddress *addr,
                                                         GMainContext *async_context,
                                                         SoupAddressCallback callback,
                                                         gpointer user_data);

Like soup_address_resolve_async(), but calls callback from the given async_context.

addr :

 a SoupAddress

async_context :

 the GMainContext to call callback from

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_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.

addr :

 a SoupAddress

len :

 return location for sockaddr length

Returns :

 the sockaddr, or NULL

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
