Subject: Progress: Continue string and convert changes, fixing bugs.
X-Git-Tag: 0.5.5~17
X-Git-Url: https://git.kevux.org/?a=commitdiff_plain;h=2eaa1b50d6d15e530fbb1635958aa190dfe7f9df;p=fll

Progress: Continue string and convert changes, fixing bugs.

Update all relevant dependencies.

Convert the error projects.
Convert control program.
Begin converting controller program.

I really wanted to get rid of those pesky mutex locks.
With the addition of explicit calls to flockfile() and funlockfile() this felt like a possibility.
Unfortunately, I still need to protect both stdout and stderr from both writing to the same destination (which is common for normal consoles).
