Subject: src/utils_threshold.[ch]: Implement `ut_search_threshold'.
X-Git-Tag: collectd-4.8.0~13
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=f093ce8b64e8641e4fec31478f121958f9ebe6f6;p=collectd.git

src/utils_threshold.[ch]: Implement `ut_search_threshold'.

It allows external modules to query the threshold for a specific
`value_list_t'.
