Contains a robust API for logging messages. Definition in file dlog.h.

enumdaemon_log_flags Specifies where to send the log messages to. The global variable daemon_log_use takes values of this type. EnumeratorDAEMON_LOG_SYSLOG Log messages are written to syslog. DAEMON_LOG_STDERR Log messages are written to STDERR. DAEMON_LOG_STDOUT Log messages are written to STDOUT. DAEMON_LOG_AUTO If this is set a daemon_fork() will change this to DAEMON_LOG_SYSLOG in the daemon process. Definition at line 38 of file dlog.h.

char*daemon_ident_from_argv0(char*argv0) Return a sensible syslog identification for daemon_log_ident generated from argv[0]. This will return a pointer to the file name of argv[0], i.e. strrchr(argv[0], '\')+1 Parametersargv0 argv[0] as passed to main() Returns The identification string Examplestestd.c. voiddaemon_log(intprio,constchar*t,...) Log a message using printf format strings using the specified syslog priority. Parametersprio The syslog priority (PRIO_xxx constants) t,... The text message to log Examplestestd.c. voiddaemon_logv(intprio,constchar*t,va_listap) Same as daemon_log(), but without variadic arguments. Since 0.11 SeealsoDAEMON_LOGV_AVAILABLEvoiddaemon_set_verbosity(intverbosity_prio) Setter for the verbosity level of standard output. Parametersverbosity_prio Minimum priority level for messages to output on standard output/error Allows to decide which messages to output on standard output/error streams. All messages are logged to syslog and this setting does not influence that. The default value is LOG_WARNING. Since 0.14 SeealsoDAEMON_SET_VERBOSITY_AVAILABLE
