Hi Eitan, I have just used fflush and it works.
The real problem is that C programme was just a test programme. I am
using someone else's programme and I only have the binary! This makes
life complicated. The only way will be to try and unbuffer output and
then launch the c binary so that it inherits the unbuffereing that I
have set.
AFAICT, there's no way to do that. The launched C program won't
inherit any buffering setting. The problem is easily solved if
you've
got the C code and can insert a single call to 'setvbuf'. Or simply
inline the code via Perl's Inline::C.
Otherwise, you'll have to use the suggested 'Expect' module so the
C program thinks it's talking to a terminal rather than through a
pipe.

Thanks Charles, yup I I actually didn't think it was possible but I have
installed the Expect and Expect-simple modules. Will do a bit of reading
there. The C programme I am actually trying to control is jigdo-file. I
get some errors on file server on night time scheduled downloads, so I
want to contol them as much as possible, making sure the Debian
(testing) images I download are all from the same week, checksum errors
etc. Thanks a lot,
Cheers,
Rob Key
