Subject: metaplugin: Add PrevJobName parameter to JobInfo.
X-Git-Tag: Release-11.3.2~496
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e290adf51c740b402a4aa335367c4f181e321f55;p=thirdparty%2Fbacula.git

metaplugin: Add PrevJobName parameter to JobInfo.

If you want to add an automatic JobInfo variable then main plugin
file should define the following variable:
const bool CUSTOMPREVJOBNAME = true;
This variable is now required for a successful build of the plugin.
