/**
 * GFileOutputStream provides output streams that write their

 * GFileOutputStream implements #GSeekable, which allows the output
 * 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 output stream, use g_seekable_tell().
 * To find out if a file output stream supports seeking, use
 * g_seekable_can_seek().To position a file output stream, use
 * g_seekable_seek(). To find out if a file output stream supports
 * truncating, use g_seekable_can_truncate(). To truncate a file output
 * stream, use g_seekable_truncate().
