If drm_class_a has an aggregate requirement for drm_class_b, returns the specified requirement.
That is, if an object of DRM class A can be aggregated by an object of DRM class B via a bidirectional aggregation, the SE_Requirement that specifies the details of the relationship is retrieved.
| SE_DRM_STAT_CODE_SUCCESS | and *req_out_ptr is set appropriately, if if valid parameters were passed in. |
| SE_DRM_STAT_CODE_NULL_REQUIRED_PARAMETER | and *req_out_ptr is left unchanged, if req_out_ptr is NULL. |
| SE_DRM_STAT_CODE_INVALID_VERSION | and *req_out_ptr is set to NULL, if the specified version of the DRM is not supported. |
| SE_DRM_STAT_CODE_INVALID_CLASS | and *req_out_ptr is set to NULL, if drm_class_a or drm_class_b does not correspond to a valid DRM class in the specified DRM version. |
| SE_DRM_STAT_CODE_FAILURE | and *req_out_ptr is set to NULL, if 'drm_class_a' has no aggregates of type 'drm_class_b' in the specified DRM version. |
1 major DRM version number of the DRM version for which this function is being called
2 minor DRM version number of the DRM version for which this function is being called
3 represents the DRM class whose aggregate requirement is being requested in the specified DRM version.
4 represents requested aggregate DRM class in the specified DRM version.
