/* var.c - a typeless variable class
 *
 * This class is used to represent variable values, which may have any type.
 * Among others, it will be used inside rsyslog's expression system, but
 * also internally at any place where a typeless variable is needed.
 *
 * Module begun 2008-02-20 by Rainer Gerhards, with some code taken
 * from the obj.c/.h files.
