[htdig-dev] Re: truncated output from htsearch...a strace

[Lachlan A. <lh...@us...>]

Sorry Aaron, I don't know what could be causing the problem.  However,=20
the fact that there are fewer  write()s  when the ouput is a file is=20
to be expected.  Output is "block-buffered" if the output is not a=20
terminal, which means it saves up 4096 bytes before writing.  If the=20
output is a tty, the data is "line-buffered", which means it is=20
written after every '\n'.

There *shouldn't* be a need to flush stdout unless the program exits=20
abnormally (e.g. segfaults).  Is the resulting file a multiple of=20
4096 bytes long?  What happens if you simply pipe the output through =20
more/less?  Is it still truncated?

Good luck!
Lachlan
