<<_fstat64_r>>---Reentrant version of fstat64

_fstat64_r
SYNOPSIS
#include <reent.h>
int _fstat64_r(struct _reent *<[ptr]>,

DESCRIPTION
This is a reentrant version of <<fstat64>>. It
takes a pointer to the global data block, which holds
<<errno>>. This function is only enabled on systems
that define __LARGE64_FILES.
