Setting a name for a `std::jthread`

To set a name for a std::jthread in C++, you can make use of platform-specific features or third-party libraries. Unfortunately, there is no standard way to set a name directly on a std::jthread object, as the C++ standard library does not provide such functionality.

However, here is an example of how you can set a name for a std::jthread using the Boost library, assuming you have it installed and configured in your build environment:

#include <boost/thread.hpp>

void myThreadFunc()
{
    // Thread functionality here
}

int main()
{
    std::jthread myThread(myThreadFunc);
    boost::thread nativeThread = myThread.native_handle();

    const std::string threadName = "MyThread";
    boost::thread::native_handle_type threadHandle = nativeThread.native_handle();

    // Set the name of the thread using platform-specific code
    #ifdef _WIN32
        SetThreadDescription(threadHandle, threadName.c_str());
    #else
        pthread_setname_np(threadHandle, threadName.c_str());
    #endif

    // Rest of the program

    return 0;
}

In this example, we create a std::jthread object named myThread that executes the function myThreadFunc. We then obtain the native handle of the thread using the native_handle() function and store it in a boost::thread::native_handle_type variable.

Next, we set a name for the thread using the appropriate function depending on the platform. In this example, we use SetThreadDescription() on Windows and pthread_setname_np() on POSIX systems. Replace the platform-specific code with the appropriate function for your target platform.

By setting a name for the thread, it becomes easier to identify and track it during debugging sessions or when working with thread-specific monitoring tools.

Remember to include the necessary headers and link against the appropriate libraries when using Boost or other third-party libraries.
