File ManipulationYou can take a look at shmem if you want to map a file to memory. Haven't tried it myself yet though.

I require two things: 1. The ability to truncate and grow a file. I see the seek/write functions which I'm guessing will take care of my growth needs but what about truncation? 2. The ability to memory map a file. I saw mapped_file which I guess is the one. Simon
