 PARAMETERS

 Input

 context
        An opaque handle bound to a registry server.  Use
        sec_rgy_site_open() to acquire a bound handle.

 name_domain
        A value of type sec_rgy_domain_t that identifies the registry
        domain in which the object specified by name resides. The valid
        values are as follows:

        sec_rgy_domain_person
                    The name identifies a principal.

        sec_rgy_domain_group
                    The name identifies a group.

        sec_rgy_domain_org
                    The name identifies an organization.

 This parameter is ignored if name is policy or replist.

 name   A pointer to a sec_rgy_name_t character string containing the
        name of the person, group, or organization to which the
        attribute is attached.

 num_attr_keys
        An unsigned 32-bit integer that specifies the number of elements
        in the attr_keys array.  Set this parameter to 0 to return all
        of the object's attributes that the caller is authorized to see.

 space_avail
        An unsigned 32-bit integer that specifies the size of the
        attr_keys array.

 attr_keys[]
        An array of values of type sec_attr_t that identify the attribute
        type ID of the attribute instance(s) to be looked up. If the
        attribute type is associated with a query attribute trigger,
        the sec_attr_t attr_value field can be used to pass in optional
        information required by the attribute trigger query.  If no
        information is to be passed in the attr_value field (whether
        the type indicates an attribute trigger query or not), set the
        attribute's encoding type to sec_rgy_attr_enc_void.  The size
        of the attr_keys[] array is determined by the num_attr_keys
        parameter.

 Input/Output

 cursor
        A pointer to a sec_attr_cursor_t. As an input parameter, cursor
        is a pointer to a sec_attr_cursor_t initialized by a
        sec_rgy_attr_srch_cursor_init call. As an output parameter,
        cursor is a pointer to a sec_attr_cursor_t that is positioned
        past components returned in this call.

 Output

 num_returned
        A pointer to a 32-bit unsigned integer that specifies the number
        of attribute instances returned in the attrs[] array.

 attrs  An array of values of type sec_attr_t that contains the
        attributes retrieved by UUID. The size of the array is
        determined by space_avail and the length by num_returned.

 num_left
        A pointer to a 32-bit unsigned integer that supplies the number
        of attributes that were found but could not be returned because
        of space constraints in the attrs[] buffer.  To ensure that all
        the attributes will be returned, increase the size of the
        attrs[] array by increasing the size of space_avail and
        num_returned.

 status
        A pointer to the completion status.  On successful completion,
        the routine returns error_status_ok, or, if the requested
        attributes were not available, it returns the message
        not_all_available.  Otherwise, it returns an error.

 DESCRIPTION

 The sec_rgy_attr_lookup_by_id() function reads those attributes
 specified by UUID for an object specified by name. This routine is
 similar to the sec_rgy_attr_lookup_no_expand routine with one
 exception: for attribute sets, the sec_rgy_attr_lookup_no_expand
 routine returns a sec_attr_t for the set instance only; it does not
 expand the set and return a sec_attr_t for each member in the set.
 This call expands attribute sets and returns a sec_attr_t for each
 member in the set.

 If the num_attr_keys parameter is set to 0, all of the object's
 attributes that the caller is authorized to see are returned.  This
 routine is useful for programmatic access.

 For multi-valued attributes, the call returns a sec_attr_t for each
 value as an individual attribute instance. For attribute sets, the call
 returns a sec_attr_t  for each member of the set; it does not return
 the set instance.

 The attr_keys[] array, which specifies the attributes to be returned,
 contains values of type sec_attr_t.  These values consist of:

  +  attr_id, a UUID that identifies the attribute type

  +  attr_value, values of sec_attr_value_t that specify the attribute's
     encoding type and values.

 Use the attr_id field of each attr_keys array element, to specify the
 UUID that identifies the attribute type to be returned.

 If the attribute instance to be read is not associated with a query
 trigger or no additional information is required by the query trigger,
 an attribute UUID is all that is required. For these attribute
 instances, supply the attribute UUID in the input array and set the
 attribute encoding (in sec_attr_encoding_t) to sec_attr_enc_void.

 If the attribute instance to be read is associated with a query
 attribute trigger that requires additional information before it
 can process the query request, use a sec_attr_value_t to supply the
 requested information.

 To do this:

  +  Set the sec_attr_encoding_t to an encoding type that is compatible
     with the information required by the query attribute trigger.

  +  Set the sec_attr_value_t to hold the required information.

 Note that if you set num_attr_keys to zero to return all of the object's
 attributes and that attribute is associated with a query attribute
 trigger, the attribute trigger will be called with no input attribute
 information (that would normally have been passed in via the attr_value
 field).

 The cursor parameter specifies a cursor of type sec_attr_cursor_t
 initialized to the point in the attribute list at which to start
 processing the query.  Use the sec_attr_cursor_init function to
 initialize cursor. If cursor is uninitialized, the server begins
 processing the query at the first attribute that satisfies the search
 criteria.

 The num_left parameter contains the number of attributes that were
 found but could not be returned because of space constraints of the
 attrs[] array. (Note that this number may be inaccurate if the target
 server allows updates between successive queries.) To obtain all of the
 remaining attributes, set the size of the attrs[] array so that it is
 large enough to hold the number of attributes listed in num_left.

 Permissions Required

 The sec_rgy_attr_lookup_by_id() routine requires the query permission
 set for each attribute type identified in the attr_keys[] array. These
 permissions are defined as part of the ACL manager set in the schema
 entry of each attribute type.
