2003-07-01rewrite to not use mmap(2). solves a bunch of issues:Henning Brauer
- No more I/O related SEGVs (PR 2337?). - Performance linear to size of output, not input file size, even for very large files. Same for -r. - Reverse tail also works for very large files. - Very large values of n possible, even for very large files. Same for -r. work by Otto Moerbeek <otto@drijf.net> tested by and ok millert@ and myself

hand editing to make comments line up correctly. Another pass is forthcoming that handles the cases that could not be done automatically.

1999-08-04supply particular mapping type to the mmap(2) instead of bogus 0Michael Shalayeff
1999-04-29don't step on the tail if there is no one, or core dumps; millert - yesMichael Shalayeff
1999-02-03Fix broken conversion of private err() function and make ierr() and oerr()Todd C. Miller
back into functions, not macros. Also make functions that call mmap() return an int so we can fall back to non-mmap (slow) version on mmap failure. Noticable effects: o when you tail multiple files, if one of the files doesn't exist or is otherwise broken, keep on going to the next file. o it is now possible to tail files > 2gig, though it will be *very* slow since tail will be unable to use mmap()
1997-01-12Fix core dump and use libc err(3) instead of private one (which hadTodd C. Miller
slightly different semantics). Also clean up some gcc -Wall'isms.
