Subject: bugfix of error handling while open()
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=cac289316bed4282f798dbe710398e6f53f66f1f;p=oweals%2Fprocd.git

bugfix of error handling while open()

The normal return value from open() is a non-negative integer.
In the case of an error, a value of -1 is returned instead.
