Similar to g_file_query_info(), but obtains information
about the filesystem the file 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.
