measure_disk_usage

Recursively measures the disk usage of this.

This is essentially an analog of the 'du' command, but it also reports the number of directories and non-directory files encountered ( including things like symbolic links).

By default, errors are only reported against the toplevel file itself. Errors found while recursing are silently ignored, unless g_file_disk_usage_report_all_errors is given in flags.

The returned size, disk_usage, is in bytes and should be formatted with g_format_size in order to get something reasonable for showing in a user interface.

progress_callback and progress_data can be given to request periodic progress updates while scanning. See the documentation for FileMeasureProgressCallback for information about when and how the callback will be invoked.

Parameters:

this	a File
flags	FileMeasureFlags
cancellable	optional Cancellable
progress_callback	a FileMeasureProgressCallback
disk_usage	the number of bytes of disk space used
num_dirs	the number of directories encountered
num_files	the number of non-directories encountered
progress_data	user_data for progress_callback

Returns:

true if successful, with the out parameters set. false otherwise, with throws set.
