Subject: src/rrd_format.c: Implemented "cf_to_string"
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=00d2f049a74cfd7e6d371e2c2c187f40013fbb45;p=rrdtool.git

src/rrd_format.c: Implemented "cf_to_string"
A simple helper function to turn an "enum cf_en" to a string. The returned
pointer points to static memory and doesn't need to be freed. -- Florian
