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 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 "fs:*" means all attributes in the fs
namespace. The standard namespace for filesystem attributes is "fs".
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.
