Given the tag of a type specification,

if the type specification defines an enumerated type, then retrieve the number of enumerants in that enumerated type
if the type specification defines a struct type, then retrieve the number of fields in that struct
if the tag was invalid, then return SE_DRM_STAT_CODE_INVALID_TYPE

SE_DRM_STAT_CODE_SUCCESS	and *result_out_ptr is set appropriately, if valid parameters were passed in.
SE_DRM_STAT_CODE_NULL_REQUIRED_PARAMETER	and *result_out_ptr is left unchanged, if result_out_ptr is NULL.
SE_DRM_STAT_CODE_INVALID_VERSION	and *result_out_ptr is set to NULL, if the specified version of the DRM is not supported.
SE_DRM_STAT_CODE_INVALID_TYPE	and *result_out_ptr is set to zero (0), if drm_type does not correspond to a valid type available to the requested version of the DRM.
SE_DRM_STAT_CODE_INVALID_TYPE_CLASSIFICATION	and *result_out_ptr is set to zero (0), if drm_type corresponds to a 'basic' type.

Parameters Notes

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 a SEDRIS type, available for use by the requested version of the DRM.

⁴ pointer to a variable within the user's memory space where the answer will be stored
