Subject: email plugin: "Calculate" UNIX_PATH_MAX if it is not defined.
X-Git-Tag: collectd-3.11.0~27
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=33d409e0d68beac9d6d5439a9237b50f28fcd976;p=collectd.git

email plugin: "Calculate" UNIX_PATH_MAX if it is not defined.

Some systems (e.g. Darwin) do not seem to define UNIX_PATH_MAX at all. Thus I
calculate it from the size of the sun_path character array of struct
sockaddr_un in this case.
