New Revision: 210613
URL: http://svn.freebsd.org/changeset/base/210613
Log:
kill: Stop processing if a syntactically invalid pid is encountered.
So a command like
kill _HUP 1
now fails without sending SIGTERM to init.
The behaviour when kill(2) fails remains unchanged: processing continues.
This matches other implementations and POSIX and is useful for killing
multiple processes at once when some of them may already be gone.
