Method

GioFileenumerate_children

Declaration [src] 

GFileEnumerator*
g_file_enumerate_children (
  GFile* file,
  const char* attributes,
  GFileQueryInfoFlags flags,
  GCancellable* cancellable,
  GError** error
)

Description [src]

Gets the requested information about the files in a directory. The result is a GFileEnumerator object that will give out GFileInfo objects for all the files in the directory.

The attributes value is a string that specifies the file attributes that should be gathered. It is not an error if it’s not possible to read a particular requested attribute from a file - it just won’t be set. attributes should be a comma-separated list of attributes or attribute wildcards. The wildcard “” means all attributes, and a wildcard like “standard::” means all attributes in the standard namespace. An example attribute query be “standard::*,owner::user”. The standard attributes are available as defines, like G_FILE_ATTRIBUTE_STANDARD_NAME. G_FILE_ATTRIBUTE_STANDARD_NAME should always be specified if you plan to call g_file_enumerator_get_child() or g_file_enumerator_iterate() on the returned enumerator.

If cancellable is not NULL, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error G_IO_ERROR_CANCELLED will be returned.

If the file does not exist, the G_IO_ERROR_NOT_FOUND error will be returned. If the file is not a directory, the G_IO_ERROR_NOT_DIRECTORY error will be returned. Other errors are possible too.

Parameters

attributes

Type: const char*

An attribute query string.

The data is owned by the caller of the method.
The value is a NUL terminated UTF-8 string.
flags

Type: GFileQueryInfoFlags

A set of GFileQueryInfoFlags.

cancellable

Type: GCancellable

Optional GCancellable object, NULL to ignore.

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

A GFileEnumerator if successful, NULL on error. Free the returned object with g_object_unref().

The caller of the method takes ownership of the returned data, and is responsible for freeing it.
