    SubjectUnswappable memory needed is user space
    I'm making a crypto program (under french law).
    It crypts a file and then totally erase the uncrypted by filling it with
    zero.

    My problem is that if the crypting process is swapped out during
    crypting, one could be able to recover parts of uncrypted file
    in swap partition.

    Is there a way to malloc a non swappable part of memory ?
