Subject: src/utils_db_query.c: Correctly handle return value of strjoin().
X-Git-Tag: collectd-5.6.0~3^2~5^2~1
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=e5ec04602ccc08aa45d8a9e60d9bcb476d3f9655;p=collectd.git

src/utils_db_query.c: Correctly handle return value of strjoin().

It returns the number of bytes, not zero, on success. This fixes a
bug introduced in 496ca2b758344bc6372ab0adf98ad8050f69b25a.
