From: bluhm Date: Wed, 5 Apr 2017 21:30:04 +0000 (+0000) Subject: The function logmsg() was used to generate local messages and to X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=1106b6acd5b561f760d206ce311a69c5979f19af;p=openbsd The function logmsg() was used to generate local messages and to process incoming messages. Split this functionality into log_info() and logline(). Sort the parameters like they appear in the syslog line.
