GObjectsignal_emitv

void
g_signal_emitv (
  const GValue* instance_and_params,
  guint signal_id,
  GQuark detail,
  GValue* return_value
)

Emits a signal.

Note that g_signal_emitv() doesn’t change return_value if no handlers are connected, in contrast to g_signal_emit() and g_signal_emit_valist().

`instance_and_params`	An array of `GValue`
	Argument list for the signal emission. The first element in the array is a `GValue` for the instance the signal is being emitted on. The rest are any arguments to be passed to the signal.
	The data is owned by the caller of the function.
`signal_id`	`guint`
	The signal id.
`detail`	`GQuark`
	The detail.
`return_value`	`GValue`
	Location to store the return value of the signal emission. This must be provided if the specified signal returns a value, but may be ignored otherwise.
	The argument will be modified by the function.
	The argument can be `NULL`.
	The called function takes ownership of the data, and is responsible for freeing it.
