Retrieves all structural information about a class.
NOTE: The individual pieces of the structural information can be retrieved using the following sample code:
c_count = SE_ClassCount();
for (class_indx = SE_CLS_DRM_NULL; class_indx < c_count; class_indx++)
{
status_code = SE_FieldCountForClass(class_indx, &fc);
if (status_code == SE_DRM_STAT_CODE_SUCCESS)
{
for (i = 0; i < fc; i++)
status_code = SE_ithFieldInClass(class_indx, i, &field_ptr)
}
}
| SE_DRM_STAT_CODE_SUCCESS | 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_CLASS | and *result_out_ptr is set to NULL, if drm_class does not correspond to a valid DRM class. |
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 DRM class in the specified DRM version.
4 pointer to variable in the user's memory space where the answer (a pointer) will be stored.
