What's a real program?  I consider awk, perl, sort, grep and so on
to be real programs.  They can all take input from stdin, even when that
is connected via a pipe.

Maybe the issue is with the way Windows shells connect tools together.
If modern shells still fake pipes using files, then insisting that all
inputs be seek-able (or stat-able) will not show up as an issue.  Maybe
it is virtually impossible to give a Windows program a non-seekable
input?  This would surprise me, because pipes give one a natural way to
use multi-core processors.

Note that I'm not saying that the Windows versions of, say awk and perl
do anything other than treat their inputs as proper streams.  I'm just
saying that the tools you write might not show up as being any less
capable than these because of the way the shell connects them up.

I have no idea what you mean here.  I am suggesting that C programs can
easily be written so that they handle any inputs.  If the programmer
wants to do that using a "read_whole_stream" function, that can be
written so as to be universal at very little extra cost.  I don't see
why you keep advocating the method of getting the size first since it
has very little benefit.

I don't know where this comes from.  I'm talking about very ordinary
programs that read and process stream from start to finish, some of
which will need or want the whole input before doing anything with it
(like your reverse example).

Only the middle column is interesting here since this is an OS+C library
question.

Can you try the latest version where I was prompted to try the POSIX
functions that avoid FILE object locking?  The unlocked gets version
was, on Linux, even faster that the other which is not unexpected since
the others do more work.

You may have to poke about a bit to find out what Windows calls these
unlocked IO functions is the libc your are using does not provide the
POSIX getc_unlocked directly.

Doesn't Windows provide a way to time a program without altering it?

Yes, it's horrendous.  I wonder how much (if any) of that is locking the
FILE structure.

But it is possible to use realloc method always, and then you never have
to think about it again.  I accept that /you/ may not care, but since
the cost is minimal you should not encourage others to write limited
stream reading functions.

Yes. I deliberately used a file with nothing but 7-bit characters since
I couldn't decide what the correction should be.  We could force a
signed value in all cases, or force and unsigned one in the buffered
cases using either an unsigned char array or a cast.  Both seemed like a
distraction from the main point.

Agreed.  You can just use a 7-bit file though.
