2GB file limit

[Ludilu]

Hi,
first of, thanks for sharing your lib, works well so far with one exception.

Do you have an idea how to work around the 2GB file limit or does it work on your end?
I tried to use _fseeki64 and _ftelli64 without success.

I am building on Windows 10 64bit using mingw-64.

Best regards

I was able to get it working.

Here are the thinks to do for future reference:

• replace fseek with _fseeki64
• replace ftell with _ftelli64
• replace all long variables in this regard with __int64

Best regards
