'C' has a limitation of 32-bit file sizes, which restricts the size of
the IFS file you can access to about 2GB.  There is a compiler option
"SYSIFCOPT(*IFS64IO)" in 'C' to enable LARGE FILE support.  

Since we have some RPG programs accessing IFS via the '_C_IFS_fopen'
procedures, does anyone know if these are also restricted to a 2GB file
size or if _LARGE_FILE support is enabled auto-magically?  If they are
restricted, can _LARGE_FILE support be enabled for them or is there a
'_C_IFS_fopen64' version of them?

Thanks
