Ft_attribute_groups

typedef Uint16 Ft_attribute_groups;

Ft_attribute_groups speciﬁes the level of support for attributes.

Attributes are grouped as either kernel, storage, security, or private.

• The kernel attributes are always present (i.e., you do not negotiate

them).

• Attributes within the storage, security, and private groups are valid

only if you negotiate that group during ft_connect().

• Response to an attribute value request (e.g., ft_cattributes()) always

includes one of the following items:

• If you request an unnegotiated attribute, the response includes no

value available and an error (result_code); may optionally include

a diagnostic.

• If the HP-UX responder partially supports the attribute, the value

(zero (0) for integers; “no value available” for strings) indicates

that there is no value available.

• If the HP-UX responder fully supports the attribute, actual values

are returned.

• For ft_rattributes() and ft_frattributes(), the attribute_names ﬁeld

defaults to indicate all attributes in the attribute_ groups negotiated

on the ft_connect() request.
