示例#1

文件： buffer.hpp 项目： aonorin/triSYCL

 /** The buffer content may be copied back on destruction to some
     final location */
 ~buffer() {
   /* If there is a final_data set and that points to something
      alive, copy back the data through the shared pointer */
   if (auto p = final_data.lock())
     std::copy_n(access.data(), access.num_elements(), p.get());
   /* If data are shared with the host but not concretely, we would
      have to copy back the data to the host */
   // else if (shared_data)
   //   std::copy_n(access.data(), access.num_elements(), shared_data.get());
 }

示例#2
