.SH DESCRIPTION
This function is similar to the 
.IR "code{lio_listio"
function.  The only
difference is that on 
.IR "32 bit"
machines, the file descriptor should
be opened in the large file mode.  Internally, 
.IR "lio_listio64"
uses
functionality equivalent to 
.IR lseek64"
to position the file descriptor correctly for the reading or
writing, as opposed to 
.IR "lseek"
functionality used in
.IR "lio_listio".

When the sources are compiled with 
.IR "_FILE_OFFSET_BITS == 64"
, this
function is available under the name 
.IR "lio_listio"
and so
transparently replaces the interface for small files on 32 bit
machines.
