Top Forums Programming Is there a system call other than 'open' for opening very large files? Post 302344308 by jim mcnamara on Saturday 15th of August 2009 07:12:57 PM

Your system should have something like fopen64() or something that enables largefiles.

try man largefile (or man largefiles), which will show you what support is available. In some cases setting an environment variable or a cc option (both during compile time) allows open to access huge files.

You did not mention your OS. That would help - a lot.
