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.

◆ THREAD_NAME

#define THREAD_NAME "log"

Typedef Documentation

◆ janus_log_buffer

typedef struct janus_log_buffer janus_log_buffer

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()

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.
