Subject: bugfix: initialize pid (as read from pidfile) to zero
X-Git-Tag: release-1.0.10~76
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=cdf7f13c31310da0c40819fd812e19519bf4318c;p=oweals%2Ftinc.git

bugfix: initialize pid (as read from pidfile) to zero

If we didn't read any number from a pid file, we'll return
an unitialized variable to the caller, and it will treat
that garbage as a pid of a process (possible to kill).

Fix that.
