- * Purpose: This function is a wrapper for the H5AC_protect call. The

- * for FPHDF5. (It'd get a read lock on an object but once
- * it got that object, it'd release it keeping the old

- * since the pointer into some metdata block can become
- * invalid.)

- * N.B.: This function is always called in conjunction with
- * the H5HL_offset_into function. The return from that
- * function is the proper pointer to the heap's object. This
- * is done so that the return from this function can be sent
- * to H5HL_unprotect.
- *
- * Return: Success: Ptr to the object. The pointer points to a
- * chunk of memory large enough to hold the
- * object from the specified offset (usually the
- * beginning of the object) to the end of the
- * object. Do not attempt to read past the end
- * of the object.
