Re: Buffered reading of stream files

Hi Adam,

Perhaps 2 years ago, I wrote some routines intended to solve the same sort of problem when working with sockets. (Where fopen, fread, fgets, et al isn't available.)

I didn't mention this before because you said you already had your own buffering routines -- so I figured you wouldn't care much about my buffering routines :)

But the more I think of it, the more it makes sense to compare notes. Perhaps I could send you what I've done (off-list) and you could run your benchmarks over my routines for comparison? Of course, my tools are aimed at sockets rather than IFS, but small modifications should make IFS possible...

Seems my response last night didn't get through.

What happens if you change it to use fgetc() instead of fread()?

Changing to fgetc() from fread() didn't make much difference. Again in
microseconds:

5780000
5691000
5682000
5737000
5745000

I think my method of adding one byte at a time to the record might be a
bit naive. I'll probably play around with these a bit more and see if I
can improve things a bit. I think that fopen() family would be much
more on par if I could add the assumption of one record per line (which
doesn't seem all that unreasonable).

Thanks to all for your suggestions and help so far.
