  CPMFindPackage(
    NAME           lockpp
    VERSION        2.8
    GIT_REPOSITORY "https://github.com/Curve/lockpp"
  )

• Using FetchContent

  target_link_libraries(<target> cr::lockpp)

📃 Usage

lockpp::lock<std::string> var("Test");

// Read only access
{
    auto locked = var.read();
    assert(!locked->empty());
}

// Write access
{
    auto locked = var.write();

    *write_access = "assignment";
    locked->clear();
}

// One time access
var.assign("another assignment");
assert(var.copy() == "another assignment");

lockpp also allows you to supply the mutex to be used as well as custom locks (i.e std::unique_lock, std::lock_guard).
