Tested on a Linux system:

┌─[roger@snoopy]─[~/descargas/bryant]
└──► $ uname -a
Linux snoopy 6.6.58-gentoo-r1-roger #1 SMP PREEMPT_DYNAMIC Wed Nov  6 11:59:48 UTC 2024 x86_64 Intel(R) Xeon(R) E-2288G CPU @ 3.70GHz GenuineIntel GNU/Linux

└──► $ g++ --version
g++ (Gentoo 13.3.1_p20241025 p1) 13.3.1 20241024


To build run make.


Generate 100000 random lines in a file name original.txt:

    ./gen-file.py 100000


Test reverser, running 4 threads, processing chunks of 10000 bytes per thread iteration:

    ./thing original.txt reversed.txt 4 10000

Undo:

    ./thing reversed.txt unreversed.txt 4 10000


Check:

    ┌─[roger@snoopy]─[~/descargas/bryant]
    └──► $ ./check-equal.sh original.txt unreversed.txt
    The file "original.txt" is the same as "unreversed.txt"
