From cbd51314c3245174b42070a66089b27472486b00 Mon Sep 17 00:00:00 2001 From: Alexander Mohr Date: Wed, 16 Dec 2020 17:31:50 +0100 Subject: bug-fix: fix invalid file descriptor check Some functions validated file descriptor to be greater 0. If a process is started without stdin, stdout and stderr the first file descriptor allocated by the process will be 0. This also will be the case if the above mentioned file descriptors will be closed on purpose. As 0 is a valid fd, some methods had to be changed to reflect this.
