Function Documentation

void close_logbuffer ( void )

Closes the logbuffer.

Definition at line 172 of file log.c.

References logbuffer, logbuffer_shm, and shmlogname.

Referenced by init_logging(), and open_logbuffer().

void debuglog	(	char *	fmt,
			...
	)

Logs the given message to stdout while prefixing the current time to it, but only if debug logging was activated.

void void errorlog	(	char *	fmt,
			...
	)

Logs the given message to stdout while prefixing the current time to it.

bool get_debug_logging ( void )

Checks if debug logging is active.

Definition at line 193 of file log.c.

References debug_logging.

Referenced by cmd_debuglog().

void init_logging ( void )

Initializes logging by creating an error logfile in /tmp (or XDG_RUNTIME_DIR, see get_process_filename()).

Definition at line 81 of file log.c.

References close_logbuffer(), errorfile, errorfilename, get_process_filename(), logbuffer, open_logbuffer(), purge_zerobyte_logfile(), and shmlog_size.

Referenced by cmd_shmlog(), and main().

Here is the call graph for this function:

void open_logbuffer ( void )

Opens the logbuffer.

Definition at line 106 of file log.c.

References close_logbuffer(), i3_shmlog_header::condvar, logbuffer, logbuffer_shm, logbuffer_size, loglastwrap, logwalk, min(), sasprintf(), shmlog_size, shmlogname, and store_log_markers().

Referenced by init_logging().

Here is the call graph for this function:

void void void void purge_zerobyte_logfile ( void )

Deletes the unused log files.

Useful if i3 exits immediately, eg. because –get-socketpath was called. We don't care for syscall failures. This function is invoked automatically when exiting.

Definition at line 331 of file log.c.

References errorfilename.

Referenced by cmd_restart(), and init_logging().

void set_debug_logging ( const bool _debug_logging )

Set debug logging.

Definition at line 201 of file log.c.

References debug_logging.

Referenced by cmd_debuglog(), and main().

void set_verbosity ( bool _verbose )

Set verbosity of i3.

If verbose is set to true, informative messages will be printed to stdout. If verbose is set to false, only errors will be printed.
