What's the line which gives you the error? When I tried to compile your code, it actually compiled it without warnings/errors.

}

The only thing I'm not sure about is CreateVehicleEx function. You set the size of the array and then you assign about the owner's name. I'd use strcpy, YSI contains it already.
