fopen large file (tera byte) support?
 

Hello Group,

I have to support 200 Gigabyte support to open a file in my program.
My program exits with

open("/mnt/d1/tmp/<file name>", O_RDONLY) = -1 EFBIG (File too large)

This open system call is a result of fopen C++ library call, and there
is no way I can provide

O_LARGEFILE mode in fopen call.

Also the return valud of fopen is a file handle, where open system
call returns the file descriptor and hence I can not substitute one vs
other.

Is there a way I can get around this problem.

Thanks.

is fdopen OR _fdopen available on your compiler?

comp.unix.programmer would be a better place to ask.
