I think you can using assembly .(the interrupt of dos or bios)

This is platform specific and so you need to ask the correct news group.

The two leading platforms are *NIX (Solaris, IRIX, Linux) and win32 the
API's are:

open()/read()/write() for *nix

for win32:

CreateFile()/ReadFile()/WriteFile()

The pre-pre alpha austria C++ library has a cross platform way of
dealing with them:

Including handling asynchronous I/O.

Hoping to full you full of grats.

Whatever you are trying to do, you are probably looking
in the wrong place. It would be very helpful to know why
you need to do such a thing, so that we can point you
in the right direction.

There are many methods to avoid the standard library,
but the right one will be dependent on what you are
really trying to to, and what platform you are trying
to do it on. It could be anything from interfacing to
the OS at a lower level, or even talking to the hardware
itself.

I'd advise including more relevant information, and
posting to a more appropriate newsgroup.

There was an article about how to compile c++ with libc only (ie no stl)
on pro-linux.de. Maybe you had that in mind? Apparently it was on
german², but teh three or four compiler flags may be extracted from the
text easily even by non-germans.
