* Function: diff_attr

* Purpose: compare attributes located in LOC1_ID and LOC2_ID, which are
* obtained either from
* loc_id = H5Gopen2(fid, name, H5P_DEFAULT);
* loc_id = H5Dopen2(fid, name);
* loc_id = H5Topen2(fid, name, H5P_DEFAULT);
*
* Return: number of differences found
*
* Programmer: Pedro Vicente, pvn@ncsa.uiuc.edu

* Date: November, 03, 2003
*
* Modifications:
* March, 02, 2007: return the number of differences found
