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

janus_log_destroy()

void janus_log_destroy

(

void

)

Log destruction.

janus_log_get_logfile_path()

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

janus_log_init()

void 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

janus_log_is_logfile_enabled()

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

janus_log_is_stdout_enabled()

gboolean janus_log_is_stdout_enabled

(

void

)

Method to check whether stdout logging is enabled.

Returns

TRUE if stdout logging is enabled, FALSE otherwise

janus_log_set_loggers()

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

janus_vprintf()

void janus_vprintf	(	const char *	format,
			... )

Buffered vprintf.

Parameters

[in]

format

Format string as defined by glib, followed by the optional parameters to insert into formatted string (printf style)

Note

This output is buffered and may not appear immediately on stdout.
