Function Documentation

begin_log_rotation()

void turi::begin_log_rotation	(	std::string	log_file_name,
		size_t	log_interval,
		size_t	truncate_limit
	)

Sets up log rotation. The basic procedure is that it will generate files of the form

*   [log_file_name].0
*   [log_file_name].1
*   [log_file_name].2
*   etc.
* 

When truncate_limit is set, a maximum number of files is maintained. Beyond which, older files are deleted.

A symlink [log_file_name].current is also created which always points to the most recent log file.

If log rotation has already been set up, this will stop the the log rotation and begin a new one.

Not safe for concurrent use.

Parameters

log_file_name	The prefix to output to. Logs will emit to [log_file_name].0, [log_file_name].1, etc.
log_interval	The number of seconds between rotations
truncate_limit	The maximum number of files to maintain. Must be >= 1
