realpath的使用

int main() {
    char image_real_path[2048];
    void *buff = nullptr;
    float *d = reinterpret_cast<float *>(buff);
    std::string image_path = "/home/huawei/CLionProjects/untitled14/cmake-build-debug/Makefile";
    auto res = realpath(image_path.c_str(), image_real_path);
    std::cout << "Hello, World!" << std::endl;
    return 0;
}
