Function Documentation

Initializes the logging module.

Parameters

info_to_stdout	`true` to log messages at a the `INFO` level to standard output.
warning_to_stdcout	`true` to log messages at a the `WARNING` level to standard output.
error_to_stdcout	`true` to log messages at a the `ERROR` (including `FATAL`) level to standard output.
verbose_to_stdcout	`true` to log messages at a the `ERROR` (including `FATAL`) level to standard output.
log_file	A string specifying the name of log file. Three different values are accepted: "": an empty string, indicating that no log file will be created. "default": create a log file with a title in the form "AppName.log" next to the executable file. any non-empty string: (if it is a valid path) a log file with the same name will be created and log messages will be written to this file.
verbosity_threshold	A `VLOG(level)` with `level` <= `verbosity_threshold` will be written into the log file (if specified). Value must be in the range [0, 9]. Default is 0.

Note: This initialization is optional. If not called, log messages will be written to standard output only.
