The printconf function allows getting a variable without clobbering the
global variable with te same name. This can be used for a per-handler
override of a global variable, e.g. local_foo=`printconf "foo" "$foo"`
-# sets a global var with name equal to $1
-# to the value of the configuration parameter $1
-# $2 is the default.

-function getconf() {
+# Retrieves the configuration variable named $1 from the current config
+# file and section and echoes its value. If it is empty or not found, $2
+# is used.
+function printconf() {
CURRENT_PARAM=$1
ret=`@AWK@ -f $libdirectory/parseini S=$CURRENT_SECTION P=$CURRENT_PARAM $CURRENT_CONF_FILE`
# if nothing is returned, set the default
CURRENT_PARAM=$1
ret=`@AWK@ -f $libdirectory/parseini S=$CURRENT_SECTION P=$CURRENT_PARAM $CURRENT_CONF_FILE`
# if nothing is returned, set the default
