    How to get Memory Address of a File in HardDisk

    I made a text file.
    I can do all File I/O functions in c. no problem!
    except that "I want to get the memory address of the begining of that File", so that I can access each character of the file by incrementing memory address.
    How to?

    Just a Learning Experiment

    The nearest you get to having a file with a memory address is through something like
    mmap(2) - Linux manual page
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
