{
char str[20];
printf ("DLL global int value : %d\n",GetDllInt());
GetDllString(str);
printf ("DLL global String value : %s\n",str);
SetDllInt(1008);
SetDllString("HelloWorld");
printf ("DLL global int value : %d\n",GetDllInt());
GetDllString(str);
printf ("DLL global String value : %s\n",str);
printf("Press any key to exit.\n");
getchar();
return 0;
