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.
