GioFilemeasure_disk_usage

Declaration 

gboolean
g_file_measure_disk_usage (
  GFile* file,
  GFileMeasureFlags flags,
  GCancellable* cancellable,
  GFileMeasureProgressCallback progress_callback,
  gpointer progress_data,
  guint64* disk_usage,
  guint64* num_dirs,
  guint64* num_files,
  GError** error
)

Description

Recursively measures the disk usage of file.

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_MEASURE_REPORT_ANY_ERROR 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 GFileMeasureProgressCallback for information about when and how the callback will be invoked.

Available since: 2.38

Parameters

flags

Type: GFileMeasureFlags

GFileMeasureFlags.

cancellable

Type: GCancellable

Optional GCancellable.

The argument can be NULL.
The data is owned by the caller of the function.
progress_callback

Type: GFileMeasureProgressCallback

A GFileMeasureProgressCallback.

The argument can be NULL.
progress_data

Type: gpointer

User_data for progress_callback.

The argument can be NULL.
The data is owned by the caller of the function.
disk_usage

Type: guint64*

The number of bytes of disk space used.

The argument will be set by the function.
The argument can be NULL.
num_dirs

Type: guint64*

The number of directories encountered.

The argument will be set by the function.
The argument can be NULL.
num_files

Type: guint64*

The number of non-directories encountered.

The argument will be set by the function.
The argument can be NULL.
error

Type: GError **

The return location for a recoverable error.

The argument can be NULL.
If the return location is not NULL, then you must initialize it to a NULL GError*.
The argument will left initialized to NULL by the method if there are no errors.
In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.

Return value

Type: gboolean

TRUE if successful, with the out parameters set. FALSE otherwise, with error set.
