  • llfio

    P1031 low level file i/o and filesystem library for the C++ standard

    There are ten examples of use within https://github.com/ned14/llfio/tree/develop/example which are hopefully self explanatory with a bit of study.

  • mio

    Cross-platform C++11 header-only library for memory mapped file IO (by vimpunk)

    I could, but it's not what I want. For memory mapping there's a nice small cross-platform library called mio.

  • fast_io

    Freestanding fast input/output for C++20 (by cppfastio)

    Are you asking fast_io ???

  • libuv

    Cross-platform asynchronous I/O

  • RapidJSON

    A fast JSON parser/generator for C++ with both SAX/DOM style API

    And documentation in most cases is more user-friendly if you will use something like MkDocs(based on Markdown), example http://rapidjson.org/
