/**
 * GFileIOStream provides io streams that both read and write to the same
 * file handle.
 *
 * GFileIOStream implements GSeekable, which allows the io
 * stream to jump to arbitrary positions in the file and to truncate
 * the file, provided the filesystem of the file supports these
 * operations.
 *
 * To find the position of a file io stream, use
 * g_seekable_tell().
 *
 * To find out if a file io stream supports seeking, use g_seekable_can_seek().
 * To position a file io stream, use g_seekable_seek().
 * To find out if a file io stream supports truncating, use
 * g_seekable_can_truncate(). To truncate a file io
 * stream, use g_seekable_truncate().
 *
 * The default implementation of all the GFileIOStream operations
 * and the implementation of GSeekable just call into the same operations
 * on the output stream.
