Subject: store: Added sdb_store_in_matcher().
X-Git-Tag: sysdb-0.6.0~88
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=e4925baf923191b68f211354f57e743b7500d0c8;p=sysdb.git

store: Added sdb_store_in_matcher().

This function creates a matcher which matches if the right value evaluates to
an array value and the left value is included in that array.
