class WireSyncClientImpl

Defined at line 516 of file fidling/gen/sdk/fidl/fuchsia.net.interfaces/fuchsia.net.interfaces/cpp/fidl/fuchsia.net.interfaces/cpp/wire_messaging.h

Methods to make a sync FIDL call directly on an unowned handle or a

const reference to a |::fidl::ClientEnd

::fuchsia_net_interfaces::Watcher>|,

avoiding setting up a client.

Public Methods

::fidl::WireResult< ::fuchsia_net_interfaces::Watcher::Watch> Watch ()

Hanging get for an interface addition/deletion change.

Clients should only have one call of this method at a time; a second

call to this method while a call is already pending will cause the

server end of the protocol to be closed.

If there are N interfaces present at the time the server end of the

protocol is initialized, then the first N invocations of this method

will return [`Event.existing`] followed by a single [`Event.idle`]

indicating that all existing interfaces have been sent. Subsequent calls

will immediately return if there is a change to be reported, or block

until a change occurs.

The server may choose to coalesce property change events, e.g. when

multiple independent property changes occur. As a result, clients cannot

assume that the order in which they observe the interface changes is the

order in which the changes occurred.

- response `event` the interface change event.

Allocates 16 bytes of request buffer on the stack. Response is heap-allocated.
