"On modern operating systems mmap is typically preferred to the System V IPC Shared Memory facility"

What does the term "modern" refer to in this statement? It's being used as a synonym for "UNIX-like" in this case, and not operating systems of recent design (which is what one would normally think of in regard to being modern). 74.134.226.55 01:08, 9 May 2007 (UTC)[reply]

Perhaps "modern implementations of UNIX and UNIX-like operating systems" would have been more precise. However, it's being compared to SysV "shared memory" which puts it obviously in the context of UNIX systems. Also mmap() as a system call (operating system function) is already strongly associated with UNIX-like operating systems. MS-Windows (and OS/2) derived their inspiration for their versions of this function from UNIX; MacOS X is a UNIX-like operating system. Are there any more "modern" operating systems which implement mmap() specifically? What other mechanisms for shared memory or memory mapped file access are available on other operating systems?

I'm not qualified to discuss the precise relative merits of Sys-V style Shared memory and mmap, but "modern operating systems" can't directly mean UNIX-like in this context because System V was UNIX, and System V methodologies would naturally have been preferred on Systev V. It may well refer to "modern UNIX-like operating systems" but it must mean that they are of sufficiently recent design to incorporate both mmap and System V stuff.

Thanks alot for the great article. I am truly impressed at how useful and eady to understand it was. God Bless You guys. By the way, wikipedia is used daily by me as I learn programming. 71.175.58.214 19:55, 6 October 2007 (UTC)[reply]

Disambiguation?

.mmap is also the file extension used by popular mind-mapping software Mindjet MindManager (Mac & PC). --86.135.209.73 (talk) 22:38, 10 September 2008 (UTC)[reply]

Compared to the subject, that is completely obscure and trivial.

History

What is the first use of mmap and first mmap-like functionality? 4.1cBSD? 91.154.87.201 (talk) 15:32, 23 March 2012 (UTC)[reply]
