Virtual Method

GioSocketAddressEnumeratornext

Declaration [src]

GSocketAddress*
next (
  GSocketAddressEnumerator* enumerator,
  GCancellable* cancellable,
  GError** error
)

Description [src]

Retrieves the next GSocketAddress from enumerator. Note that this may block for some amount of time. (Eg, a GNetworkAddress may need to do a DNS lookup before it can return an address.) Use g_socket_address_enumerator_next_async() if you need to avoid blocking.

If enumerator is expected to yield addresses, but for some reason is unable to (eg, because of a DNS error), then the first call to g_socket_address_enumerator_next() will return an appropriate error in *error. However, if the first call to g_socket_address_enumerator_next() succeeds, then any further internal errors (other than cancellable being triggered) will be ignored.

Parameters

cancellable

Type: GCancellable

Optional GCancellable object, NULL to ignore.

The argument can be NULL.

The data is owned by the caller of the method.

error

Type: GError **

The return location for a recoverable error.

The argument can be NULL.

If the return location is not NULL, then you must initialize it to a NULL GError*.

The argument will be left initialized to NULL by the virtual function if there are no errors.

In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.

Return value

Type: GSocketAddress

A GSocketAddress (owned by the caller), or NULL on error (in which case *error will be set) or if there are no more addresses.

The caller of the method takes ownership of the returned data, and is responsible for freeing it.

The return value can be NULL.
