First of all am quite new to cpp especially under linux.
I am currently working on a small project under Linux and am having to deal with large number of data(larger than 1 GB). numerous number of operation is to be done with these data. for example: sorting, searching, comparing ... etc. so in order to perform all these operations it is important that these data are in the memory...
in order to deal with such a large amount of data am thinking of using a memory mapped file..
can anyone help me or guide me in the steps of creating a memory mapped file?
Memory Mapped Files are typically used when an existing implementation (or other requirement) DICTATES that the operation must be performed on "files", and you are looking for a faster media than disk.
A memory mapped solution will never be smaller or faster than an optimal object based implementation.
So, before getting into the "how" can you explain the "why?"
