Implementation of a simple buffered logger designed to remove I/O wait from threads that may be sensitive to such delays. Buffers are saved and reused to reduce allocation calls. The logger output can then be printed to stdout and/or a log file. If external loggers are added to the core, the logger output is passed to those as well.

Function Documentation

void janus_log_destroy

(

void

)

Log destruction.

char* janus_log_get_logfile_path

(

void

)

Method to get the path to the log file.

Returns

The full path to the log file, or NULL otherwise

int janus_log_init	(	gboolean	daemon,
		gboolean	console,
		const char *	logfile
	)

Log initialization.

Note

This should be called before attempting to use the logger. A buffer pool and processing thread are created.

Parameters

daemon	Whether the Janus is running as a daemon or not
console	Whether the output should be printed on stdout or not
logfile	Log file to save the output to, if any

Returns

0 in case of success, a negative integer otherwise

gboolean janus_log_is_logfile_enabled

(

void

)

Method to check whether file-based logging is enabled.

Returns

TRUE if file-based logging is enabled, FALSE otherwise

gboolean janus_log_is_stdout_enabled

(

void

)

Method to check whether stdout logging is enabled.

Returns

TRUE if stdout logging is enabled, FALSE otherwise

void janus_log_set_loggers

(

GHashTable *

loggers

)

Method to add a list of external loggers to the log management.

Parameters

loggers

Hash table of external loggers registered in the core

			...
	)
