+ * Function: H5O_iterate

+ * Purpose: Iterate through object headers of a certain type.

+ * value of the last operator if it was non-zero, or zero if all
+ * object headers were processed.
+ *
+ * Programmer: Quincey Koziol
+ * koziol@ncsa.uiuc.edu
+ * Nov 19 2004
+ *
+ * Description:
+ * This function interates over the object headers of an object
+ * specified with 'ent' of type 'type_id'. For each object header of the
+ * object, the 'op_data' and some additional information (specified below) are
+ * passed to the 'op' function.
+ * The operation receives a pointer to the object header message for the
+ * object being iterated over ('mesg'), and the pointer to the operator data
+ * passed in to H5O_iterate ('op_data'). The return values from an operator
+ * are:
+ * A. Zero causes the iterator to continue, returning zero when all
+ * object headers of that type have been processed.
+ * B. Positive causes the iterator to immediately return that positive
+ * value, indicating short-circuit success.
+ * C. Negative causes the iterator to immediately return that value,
+ * indicating failure.
