Use one global define LOG_MAXLINE for all of them.

Remove dead code. OK jca@ deraadt@ Rename TBUF_LEN and FMT_LEN to _SIZE as they contain a NUL byte. 2017-07-20T16:58:25Z bluhm bluhm@openbsd.org 2017-07-20T16:58:25Z urn:sha1:600aaf0ece970f356e36c37a626bf6328d9fa4c6 Change FMT_SIZE to 1024+1 for consistency. Do not loop over the format string if there is no output space left. OK deraadt@ millert@ Use the reentrant strerror_r() instead of strerror() to expand %m. 2016-10-19T16:09:24Z millert millert@openbsd.org 2016-10-19T16:09:24Z urn:sha1:6ac5adf8471ec1c4d2d0eccf88866b4654fddb19 Previously, syslog_r() would avoid calling strerror() since the latter is not reentrant.

As a result, the /dev/console opening code can be removed. ok kettenis millert beck Do not include a timestamp in the syslog message. There is no need -- 2015-10-31T02:57:16Z deraadt deraadt@openbsd.org 2015-10-31T02:57:16Z urn:sha1:1778bf5bfab38adeb6a507dfbd135daf8f1fbf3e syslogd will fill it in immediately upon reception on the other side of sendsyslog(2). Our libc only talks to our syslogd, which will fix the timestamp before forwarding. syslog_r has done this for a long time already. ok tedu bluhm
