public abstract FileInfo query_filesystem_info (string attributes, Cancellable? cancellable = null) throws Error

Similar to query_info, but obtains information about the filesystem the this is on, rather than the file itself.

For instance the amount of space available and the type of the filesystem.

The attributes value is a string that specifies the 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 "filesystem::*" means all attributes in the filesystem namespace. The standard namespace for filesystem attributes is "filesystem". Common attributes of interest are g_file_attribute_filesystem_size (the total size of the filesystem in bytes), g_file_attribute_filesystem_free (number of bytes available), and g_file_attribute_filesystem_type ( type of the filesystem).

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. Other errors are possible too, and depend on what kind of filesystem the file is on.
