alex	a3118e8c68	Sweep through the tree fixing mmap() usage: ... - Use MAP_FAILED instead of the constant -1 to indicate failure (required by POSIX). - Removed flag arguments of '0' (required by POSIX). - Fixed code which expected an error return of 0. - Fixed code which thought any address with the high bit set was an error. - Check for failure where no checks were present.

joerg	151ff8e003	Our mmap(2) has a limitation where the `offset' parameter must be ... page-aligned. cmp(1) should know about this flaw, and work around it. While i was at it, fixed an uninitialized variable as reported by -Wall.	1997-01-08 12:00:55 +00:00
dyson	b0bde11dba	When mmap is used, do an madvise(MADV_SEQUENTIAL) to make things ... go much more quickly when file input is really done. Of course, the fully cached case will make no difference.	1996-12-11 05:20:20 +00:00
