Hi Ravi, Edwin's explanation is right. My question should have read "persisting (to disk) data with pointers" - sorry about that. Also, this is probably the wrong place to post this question..(oops!). Thanks for the personal replies I got though! -Shilpa -----Original Message----- From: edwin.hold@t-online.de [mailto:edwin.hold@t-online.de] Sent: Friday, November 22, 2002 12:58 PM To: Ravi Cc: Shilpa_Bansod@nai.com; kernelnewbies@nl.linux.org Subject: Re: Persisting data with pointers Ravi wrote: >> I need to find out the ways to persist data with pointers >> (excluding usage of memory mapped files).

I think it's about memory mapped i/o, accessing devices like memory pages. the data 'will be piped' from the buffer to the storage media. Persistence (persistancy? huh?) means to store data for a longer time (kept after reboot). When accessing memory through mmap io you'll read directly from the media but funktions and data will be handled like normal memory i/o. without using read/write functions. > -Ravi.
