* nmc_client_new:

* to the NMClient instance. Note that this never fails to create
* the NMClient GObject, but depending on the return value,
* the instance was successfully initialized or not.
* @error: the error if creation fails.
* @first_property_name: the name of the first property
* @...: the value of the first property, followed optionally by more
* name/value pairs, followed by %NULL
*
* Returns: %TRUE, if the client was successfully initalized.
*
* This uses nm_client_new_async() to create a NMClient instance,
* but it iterates the current GMainContext until the client is
* ready. As such, it waits for the client creation to complete
* (like sync nm_client_new()) but it iterates the caller's GMainContext
* (unlike sync nm_client_new()). This is often preferable, because
* sync nm_client_new() needs to create an additional internal GMainContext
* that it can iterate instead. That has a performance overhead that
* is often unnecessary.
