[C400-L] RE: Default compiler setting in source

["Chris Wolcott" <CWolcott@xxxxxxxxxxxxxxxxxxxxxx>]

Tried it, didn't work for me.  It compiles but I get a NULL back from my
fopen() unless I specify 'SYSIFCOPT(*IFS64IO)' on the compile command.

I usually use this:

#define _LARGE_FILE_API
#define _LARGE_FILES

It seems to work.

------------------------------

The manual implies the compile command defines the __IFS64_IO__ macro.
There is nothing in my code that defines it. 
I even tried to #undef the directive first, and got:
*=ERROR===========> a - CZM0285 #undef cannot be used with the
predefined macro __IFS64_IO__.

Sounds like you have it defined somewhere else already.
How about:

#ifndef __IFS64_IO__
   #define __IFS64_IO__
#endif

This would ensure that it is defined whether it was declared on the
compile options (CRT* command parameters), another #include-d header
file or if it wasn't defined at all.
