From: Olivier Gayot Date: Wed, 20 Jun 2018 09:42:59 +0000 (+0200) Subject: Fix invalid handling of glob() errors on Linux X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=c64195d14728aa82e280d022e9f7ceff71cfc6c1;p=i3%2Fi3status Fix invalid handling of glob() errors on Linux The manual of glob(3) says that the function returns 0 on successful completion. Any other integer value should be considered an error, not only negative integers. In practice, *BSD systems use negative values but Linux uses positive integers.
