Question about file seeking position

Question

My previous Question is about raw data reading and writing, but a new problem arised, it seems there is no ending....

The question is: the parameters of the function

Answer 1

On Windows, use _lseeki64(), on Linux, lseek64().

I recommend to use lseek64() on both systems by doing something like this:

#ifdef _WIN32
#include 
#define lseek64 _lseeki64
#else
#include 
#endif

That's all you need.
