# HG changeset patch # User Jay Gagnon <grendel(a)linux.vnet.ibm.com&gt; # Date 1204056957 18000 # Node ID 0840762ff38237d40ca56973d3455a1b54f154b7 # Parent af61b6c75b143067444f4eefe694d1e9709d2ccb [CU] (#2) classname_from_inst Function that pulls a classname out of an instance. Nothing fancy, just saves a few lines whenever this is needed. This is used by the new std_indication stuff.
