19 | * syslogd -- log system messages | |
20 | * | |
21 | * This program implements a system log. It takes a series of lines. | |
22 | * Each line may have a priority, signified as "<n>" as | |
a49a6aba RC |
23 | * the first characters of the line. If this is |
24 | * not present, a default priority is used. | |
e677da31 RC |
25 | * |
26 | * To kill syslogd, send a signal 15 (terminate). A signal 1 (hup) will | |
27 | * cause it to reread its configuration file. | |
28 | * | |
29 | * Defined Constants: | |
30 | * | |
e677da31 | 31 | * MAXLINE -- the maximimum line length that can be handled. |
a49a6aba RC |
32 | * DEFUPRI -- the default priority for user messages |
33 | * DEFSPRI -- the default priority for kernel messages | |
