Definition

Given an object that has multiple, ordered associates of a certain DRM class, returns an SE_Object for the Nth associate of that class. ITR associates will be automatically resolved and if an ITR associate is encountered that cannot be resolved, the call will return SE_STAT_CODE_UNRESOLVED_OUTPUT_OBJECT for the n value passed in and any higher n values.


Returns

SE_RET_CODE_SUCCESS and the requested object is returned.
SE_RET_CODE_FAILURE and the status code is set appropriately if the call failed.

Status Codes

SE_Status_Code(s) when SE_RET_CODE_SUCCESS is returned:

SE_STAT_CODE_SUCCESS set if valid parameters were passed in and all operations succeeded.

SE_Status_Code(s) when SE_RET_CODE_FAILURE is returned:

SE_STAT_CODE_UNRESOLVED_OUTPUT_OBJECT set if valid parameters were passed in and valid objects are returned, but the object returned using *associate_object_out_ptr is unresolved.
SE_STAT_CODE_UNRESOLVED_INPUT_OBJECT set if from_object is an unresolved SEDRIS object.
SE_STAT_CODE_NO_OBJECT set if the from_object did not contain 'n' associate objects of the desired class.
SE_STAT_CODE_INACTIONABLE_FAILURE set if
  1. 'n' was 0 (since this is a 1-based index),
  2. an invalid value was supplied for desired_associate_class,
  3. the given class of associate is not ordered for the given from_object, or
  4. the call fails for any other reason.


Parameters Notes


from_object

 the object containing the desired component

desired_associate_class

 the DRM class of component the user wants.
    Abstract types are allowed.  The SE_DRM_CLS_NULL is not.

n

 the 'index' of that component, given an ordered list of all components
      of the desired class for the given from_object. This is a 1-based
      index.

associate_object_out_ptr

 a pointer to a variable in the user's memory
    space, to which the desired associate of the from_object will be
    copied.

link_class_object_out_ptr

 a pointer to
    a variable in the user's memory space, to which the link object
    (sometimes called the association class object) traversed to reach the
    desired associate object will be copied. If no link class object was
    attached to the link used to reach the desired associate object, then
    *link_class_object_out_ptr will be NULL.
