sec_rgy_attr_lookup_by_id-Reads a specified object's attribute(s), expanding attribute sets into individual member attributes
#include <dce/sec_rgy_attr.h> void sec_rgy_attr_lookup_by_id ( sec_rgy_handle_t context, sec_rgy_domain_t name_domain, sec_rgy_name_t name, sec_attr_cursor_t *cursor, unsigned32 num_attr_keys, unsigned32 space_avail, sec_attr_t attr_keys, unsigned32 *num_returned, sec_attr_t attrs, unsigned32 *num_left, error_status_t *status);
An opaque handle bound to a registry server. Use sec_rgy_site_open() to acquire a bound handle.
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:
The name identifies a principal.
The name identifies a group.
The name identifies an organization.
This parameter is ignored if name is policy or replist.
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.
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.
An unsigned 32-bit integer that specifies the size of the attr_keys array.
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.
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.
A pointer to a 32-bit unsigned integer that specifies the number of attribute instances returned in the attrs array.
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.
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.
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.
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.
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.
