### Virtual Method

# Gio Filemeasure_disk_usage

since: 2.38

#### Declaration [src]

    gboolean
    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 [src]

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 method.

`progress_callback`

  Type: `GFileMeasureProgressCallback`

  A `GFileMeasureProgressCallback`.

`progress_data`

  Type: `gpointer`

  User_data for `progress_callback`.

  The argument can be `NULL`.
  The data is owned by the caller of the method.

`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 be left initialized to `NULL` by the virtual function 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.
