According to sef@kithrup.COM (Sean Eric Fagan): >And, yeah, there have been times when I would have liked to have seen >a "round" file (i.e., wrapping around the end). So create a circular file subroutine library that looks at the top of the file for "maxsize,curpos\n". We use one here; it's very handy, and it's usable on all UNIX implementations with file/record locks. -- Chip Salzenberg at Teltronics/TCT <chip@tct.uucp>, <uunet!pdn!tct!chip> "Most of my code is written by myself.

We use one here; it's very handy, Yes, but then you gotta teach all the standard utilities to use your routines before you can use them on those files. Same kind of argument as Darren New's about not having a standard kind of keyed file and access method -- the structure is "private" to programs written at TCT. There are good arguments for adding "commercial" OS features to UNIX if you're going to use UNIX as a commercial OS. Balancing the arguments for and against is not as clear-cut when you don't look at it from any one standpoint. -- Ronald Khoo <ronald@robobar.co.uk> +44 81 991 1142 (O) +44 71 229 7741 (H)

From the keyboard of ronald@robobar.co.uk (Ronald S H Khoo): :Yes, but then you gotta teach all the standard utilities to use your routines :before you can use them on those files.
