Detailed Description

Buffered logging.

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.

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
daemonWhether the Janus is running as a daemon or not
consoleWhether the output should be printed on stdout or not
logfileLog 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_vprintf ( const char *  format,
  ... 
)
