25 * @short_description: File Information and Attributes
27 * @see_also: #GFile, <link linkend="gio-GFileAttribute">GFileAttribute</link>
29 * Functionality for manipulating basic metadata for files. #GFileInfo
30 * implements methods for getting information that all files should
31 * contain, and allows for manipulation of extended attributes.
33 * See <link linkend="gio-GFileAttribute">GFileAttribute</link> for more
34 * information on how GIO handles file attributes.
36 * To obtain a #GFileInfo for a #GFile, use g_file_query_info() (or its
37 * async variant). To obtain a #GFileInfo for a file input or output
38 * stream, use g_file_input_stream_query_info() or
39 * g_file_output_stream_query_info() (or their async variants).
41 * To change the actual attributes of a file, you should then set the
42 * attribute in the #GFileInfo and call g_file_set_attributes_from_info()
43 * or g_file_set_attributes_async() on a GFile.
45 * However, not all attributes can be changed in the file. For instance,
46 * the actual size of a file cannot be changed via g_file_info_set_size().
47 * You may call g_file_query_settable_attributes() and
48 * g_file_query_writable_namespaces() to discover the settable attributes
49 * of a particular file at runtime.
51 * #GFileAttributeMatcher allows for searching through a #GFileInfo for
59 #include "gfileinfo.h"
60 #include "gfileinfo-priv.h"
61 #include "gfileattribute-priv.h"
