Subject: plugin.h: Introduce the identifier_t type with pointer fields.
X-Git-Tag: collectd-5.7.0~49^2~12
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=7747e2ad9a86c2307094cd4ca3f753e46329c7a5;p=collectd.git

plugin.h: Introduce the identifier_t type with pointer fields.

This serves two purposes:
 - Allow field values of arbitrary length.
 - Reuse the identifier in other places.

Renamed identifier_t from utils_vl_lookup to lookup_identifier_t.
