 | I downloaded the source and tried to compile as a C program using Visual C++ 2005 Express. Lots of compile errors, probably all of them are solvable if you are alreay comfortable with C language. Don't expect to use that code as-is -- you will have to make code changes …  |

| | Re: error 356? what compiler are you using? I just compiled with VC++ 2005 Express and got no such error message, although I did get several others because you tried to make the return value of sizeof operator negative. Just typecase sizeof to return int and that corrects that problem. |
| | what are the errors ? Your sizeOf function doesn't work because it will always return 1. The standard C/C++ sizeof() is an operator not a function and evaluates the object at compile time, not runtime. To my knowledge there is no way to duplicate it in C. In C++ I …  |
