Gio.SocketAddressEnumerator::next

function vfunc_next(cancellable: Gio.Cancellable): Gio.SocketAddress {
}
  

Retrieves the next Gio.SocketAddress from enumerator. Note that this may block for some amount of time. (Eg, a Gio.NetworkAddress may need to do a DNS lookup before it can return an address.) Use Gio.SocketAddressEnumerator.prototype.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 Gio.SocketAddressEnumerator.prototype.next will return an appropriate error in *@error. However, if the first call to Gio.SocketAddressEnumerator.prototype.next succeeds, then any further internal errors (other than cancellable being triggered) will be ignored.
