SilcBool silc_attribute_get_object(SilcAttributePayload payload,
                                       void *object,
                                       SilcUInt32 object_size);

    Returns the already parsed attribute object from the payload
    indicated by `payload'.  Copies the data into the `object' which
    must be sent as argument (and must be of correct type and size).
    The `object_size' indicates the size of the `*object' sent.
    Returns TRUE if the `attribute' attribute was found and FALSE
    if such attribute is not present in the `payload', or the `object_size'
    is not sufficient.  See the definition of SilcAttribute for the
    list of attributes and the required object types for attributes.
    You can use silc_attribute_get_attribute to get the SilcAttribute
    type from the `payload'.
