    Callback function given to various client search functions.  The
    found entries are allocated into the `clients' list.  The list must
    not be freed by the receiver, the library will free it later.  If the
    `clients' is NULL, no such clients exist in the SILC network, and
    the `status' will include the error.  Each entry in the `clients'
    is SilcClientEntry.

    If the application stores any of the SilcClientEntry pointers from
    the `clients' list it must reference it with silc_client_ref_client
    function.

    Application must not free the returned `clients' list.
