Subject: sel/sig.c: Use `DISCARD' to ignore errors from the signal-pipe `write'.
X-Git-Tag: 2.2.4~11
X-Git-Url: https://git.distorted.org.uk/~mdw/mLib/commitdiff_plain/b05d98573ee8cd415fdb77709971960665b3e431

sel/sig.c: Use `DISCARD' to ignore errors from the signal-pipe `write'.

Annoyingly, Clang complains about the empty consequent being on one line
otherwise.  Still, this is what `DISCARD' was made for.
