Here is the call graph for this function:

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.

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.
