cannot open huge file (beyond 4GB) with fopen

[Digital Puer]

Hi, I have a 13GB file. fopen() is failing on me. The resulting perror
message is: "Value too large to be stored in data type". Can someone
sugggest a solution? Do I need to use a new file library?

I am on an AIX, 32-bit PPC architecture, in case that matters.

I'm unfamiliar with the platform, but if fopen() is already failing
before you even perform an operation on the file, your problem is with
the C library implementation.

Try a platform or library-specific newsgroup/forum/wiki/message
board/Post-It(tm) exchange network. comp.unix.aix looks promising.

Oh, and try "man fopen64".

This is system-specific, so we can't really give a definitive answer
here.

I don't know whether the "-q64" option to IBM's compiler will help.

Try comp.unix.aix.

We must do something. This is something. Therefore, we must do this.

Upgrade to Solaris.... :-)
Do I need to use a new file library?

Its possible you might find a different standard library could handle
larger files. the likely problem is that the filesize is stored in a
long, which on a 32-bit implementation is probably 32 bits ie max of
4GB.

The short answer is that this is very operating system specific, and
you'll need to ask in a group specialising in your OS.

This works. Thanks!
