## #18707 — Michael Spector — 2005-09-08T11:00:46+00:00

Hi,

I've encountered change in following code behaviour (somewhere between 5.1.0b3 and 5.1.0-HEAD):

posix_isatty (STDOUT);

Now it produces this warning: cannot seek on a pipe

The attached patch adds PHP_STREAM_FLAG_NO_SEEK to the stream flags, if it detects whether
the file descriptor is not seekable.

Thanks.
