Subject: src/plugin.h: Use __attribute__((format)) for plugin_log.
X-Git-Tag: collectd-4.4.2~11^2~4
X-Git-Url: https://git.octo.it/?a=commitdiff_plain;h=b886f9aaf7675f1f9f242a2b9dfe119ce0672d66;p=collectd.git

src/plugin.h: Use __attribute__((format)) for plugin_log.

All __attribute__'s will be automatically set to /**/ when not using the
GNU CC via a macro in src/collectd.h. This way this should be portable.
