如何将opecl编译好的程序保存在本地

直接上代码：

void save_program_binary(cl_program program, cl_device_id device, const char *filename) {
   
  cl_uint num_devices = 0;
  cl_int err_num;

  // 1, Query for number of devices attached to program
  err_num = clGetProgramInfo(program, CL_PROGRAM_NUM_DEVICES,
    sizeof(cl_uint), &num_devices, NULL);
  if (err_num != CL_SUCCESS) {
   
    printf("Error querying for number of devices.\n");
    return;
  }
  printf("num_devices: %d\n", num_devices);

  // 2, Get all of the Device IDs
  cl_device_id *devices = new cl_device_id[num_devices];
  err_num = clGetProgramInfo<
