Alexander Langer	8abdc2eb40	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.

Jordan K. Hubbard	1130b656e5	Make the long-awaited change from $Id$ to $FreeBSD$ ... This will make a number of things easier in the future, as well as (finally!) avoiding the Id-smashing problem which has plagued developers for so long. Boy, I'm glad we're not using sup anymore. This update would have been insane otherwise.	1997-01-14 07:20:47 +00:00
Joerg Wunsch	c28065c606	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
John Dyson	2ae09ad871	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

Jordan K. Hubbard	e526625999	I don't like what they did to cmp(1) in 4.4 Lite; now it whines all ... the time, even with -s. Make cmp SHUT UP about non-existant files when run with -s. Submitted by: jkh	1994-08-20 11:14:07 +00:00
