Gio.File::query_info

function vfunc_query_info(attributes: String, flags: Gio.FileQueryInfoFlags, cancellable: Gio.Cancellable): Gio.FileInfo {
}
  

Gets the requested information about specified file. The result is a Gio.FileInfo object that contains key-value attributes (such as the type or size of the file).

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.

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 Gio.IOErrorEnum.cancelled will be returned.

For symlinks, normally the information about the target of the symlink is returned, rather than information about the symlink itself. However if you pass #G_FILE_QUERY_INFO_NOFOLLOW_SYMLINKS in flags the information about the symlink itself will be returned. Also, for symlinks that point to non-existing files the information about the symlink itself will be returned.

If the file does not exist, the Gio.IOErrorEnum.not_found error will be returned. Other errors are possible too, and depend on what kind of filesystem the file is on.
