18 * Some cases use stdio, but want to flush after the write
19 * to get error handling (and to get better interactive
20 * behaviour - not buffering excessively).
22 * Of course, if the flush happened within the write itself,
23 * we've already lost the error code, and cannot report it any
24 * more. So we just ignore that case instead (and hope we get
25 * the right error code on the flush).
27 * If the file handle is stdout, and stdout is a file, then skip the
28 * flush entirely since it's not needed.
