In addition + to these functions, a couple of logging prefixes are defined as + macros: + + #define SD_EMERG "<0>" /* system is unusable */ +#define SD_ALERT "<1>" /* action must be taken immediately */ +#define SD_CRIT "<2>" /* critical conditions */ +#define SD_ERR "<3>" /* error conditions */ +#define SD_WARNING "<4>" /* warning conditions */ +#define SD_NOTICE "<5>" /* normal but significant condition */ +#define SD_INFO "<6>" /* informational */ +#define SD_DEBUG "<7>" /* debug-level messages */ + + These prefixes are intended to be used in conjunction with + stderr-based logging as implemented by systemd. If a systemd + service definition file is configured with + StandardError=journal, + StandardError=syslog or + StandardError=kmsg, these prefixes can be used + to encode a log level in lines printed. This is similar to the + kernel printk()-style logging. See + klogctl2 + for more information. + + The log levels are identical to + syslog3's + log level system. To use these prefixes simply prefix every line + with one of these strings. A line that is not prefixed will be + logged at the default log level SD_INFO. + + + Hello World + + A daemon may log with the log level NOTICE by issuing this + call: + + fprintf(stderr, SD_NOTICE "Hello World!\n"); + + + + + + + See Also + + systemd1, + sd_listen_fds3, + sd_notify3, + sd_booted3, + sd_is_fifo3, + sd_watchdog_enabled3, + daemon7, + systemd.service5, + systemd.socket5, + fprintf3, + pkg-config1 + + + + -- cgit v1.2.3-54-g00ecf
