query_info

Gets the requested information about specified this.

The result is a 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:GFile:user". The standard attributes are available as defines, like 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 g_io_error_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 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 g_io_error_not_found error will be returned. Other errors are possible too, and depend on what kind of filesystem the file is on.

Parameters:

this	input File
attributes	an attribute query string
flags	a set of FileQueryInfoFlags
cancellable	optional Cancellable object, null to ignore

Returns:

a FileInfo for the given this, or null on error. Free the returned object with unref.
