29 | * syslogd -- log system messages | |
30 | * | |
31 | * This program implements a system log. It takes a series of lines. | |
32 | * Each line may have a priority, signified as "<n>" as | |
a49a6aba RC |
33 | * the first characters of the line. If this is |
34 | * not present, a default priority is used. | |
e677da31 RC |
35 | * |
36 | * To kill syslogd, send a signal 15 (terminate). A signal 1 (hup) will | |
37 | * cause it to reread its configuration file. | |
38 | * | |
39 | * Defined Constants: | |
40 | * | |
e677da31 | 41 | * MAXLINE -- the maximimum line length that can be handled. |
a49a6aba RC |
42 | * DEFUPRI -- the default priority for user messages |
43 | * DEFSPRI -- the default priority for kernel messages | |
