Subject: Bugfix: The signal is not properly closing.
X-Git-Url: https://git.kevux.org/?a=commitdiff_plain;h=3a5a4e73f16b0285e9cfb436481835e192896ef8;p=fll

Bugfix: The signal is not properly closing.

The signal id is a file descriptor.
File descriptors are unset when at -1 rather than 0.

The not zero check is therefore invalid.
Replace that check with a check against negative one.
