Depending on the issue, it may be a Filesystem/OS limitation than a language limitation. both binary and text. The writes may be larger than 2 GB.

I have tried lseek on a a 64 bit OS and it still acts like 32 bit.

Writing very large files 50+ GB
I need to write to a file that is 50 to 250GB on all three major operating systems. I tried to use the c function pwrite64. But it is not available on the Mac.
