The above function can be moved to a library . We can probably pass the key_list to get_inst() fn.
I think I'll leave this as is. Having a getInstance() function, and then another, similar, get_inst() function is confusing. The only thing this function adds is trapping of the exception and some additional error checking. It's not much extra work to have the test case trap the exception and test for error conditions. It's possible that the calling function will want to trap the exception differently or return a different error message. -- Kaitlin Rupert IBM Linux Technology Center kaitlin@linux.vnet.ibm.com
