Subject: src/oping.c: Exit early if no host could be resolved.
X-Git-Tag: liboping-1.8.0~8
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=4c1ab318cd09b77bd8d9118c61d27afdb5933d05;p=liboping.git

src/oping.c: Exit early if no host could be resolved.

Otherwise "noping" would drop the user into an empty ncurses window,
which is very confusing, annoying and unexpected.
