What do you mean by setup stage? Do you mean when HDF5 is first built? Or something else?
Hi, Ed, Say if someone has developed a package called ABC that does some scientific calculation and uses HDF5 for data management. If the package has something called abc_init() in which it sets up the library ABC, then abc_init() can call H5Eset_auto(...) to have the automatic error messages from popping on standerr by default. Users of ABC probably do not know or do not care about the HDF5 messages. Library ABC would check the HDF5 calls return code and issue its own error messages that are meaningful to its users. -- Albert Cheng Scientific Data Technologies Group, NCSA 217-244-1955 voiceUniversity of Illinois at Urbana-Champaign 217-244-1987 fax
