- * Users of the IHXFileFormatObject interface can request
- * meta info from the file format by passing in the
- * string "AcceptMetaInfo" in the request header.
- * This property, if present, is either a delimited
- * list of requested property names or the string "*".
- * If the string is "*", then all available meta info
- * is requested. The delimiter can be either a comma
- * or a semi-colon. All meta info requested (or all
- * available if AcceptMetaInfo = "*") will then be
- * placed in the file header returned asynchronously
- * to the IHXFileFormatObject::GetFileHeader() call.
- *
- * In the function below, an IHXRequest is passed
- * in. If HX_RESULT returns HXR_OK, then the other
- * variables passed in by referenced can then be
- * examined in this order:
- *
- * If "AcceptMetaInfo" is present in the request headers,
- * then rbAcceptMetaInfoPresent will be TRUE. Otherwise,
- * it will be FALSE and rbAllMetaInfoRequested and
- * rpRequestedMetaInfo will not be altered.
- *
- * If rbAcceptMetaInfoPresent is TRUE and
- * AcceptMetaInfo = "*", then rbAllMetaInfoRequested
- * will be TRUE and rpRequestedMetaInfo will be NULL.
- *
- * If rbAcceptMetaInfoPresent is TRUE and
- * AcceptMetaInfo is a delimited string of property
- * names, then rbAllMetaInfoRequested will be FALSE
- * and rpRequestedMetaInfo will be non-NULL and will
- * contain this list of property names as ULONG32
- * properties. These property names can then be retrieved
- * by using the IHXValues::GetFirstPropertyULONG32()
- * and IHXValues::GetNextPropertyULONG32() calls.
- * Note that this does not imply that the properties
- * are necessarily ULONG32 properties - it's just
- * more convenient to make them ULONG32 properties
- * than CString or Buffer properties.
