6 * Yet Another syslog(3) API clone.
7 * Used to unify rpmError() and rpmMessage() interfaces in rpm.
18 * priorities/facilities are encoded into a single 32-bit quantity, where the
19 * bottom 3 bits are the priority (0-7) and the top 28 bits are the facility
20 * (0-big number). Both the priorities and the facilities map roughly
21 * one-to-one to strings in the syslogd(8) source code. This mapping is
22 * included in this file.
24 * priorities (these are ordered)
