From: Florian Forster Date: Thu, 3 May 2007 08:49:16 +0000 (+0200) Subject: src/types_list.c: Added a function to parse a generic list of `types'. X-Git-Tag: collectd-4.0.0~57^2~5 X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=44afad3c43217e868a2e591a20f8709afe3874ed;p=collectd.git src/types_list.c: Added a function to parse a generic list of `types'.
