SUMMARY
=======


The Run-Time Library Reference descriptions for the _inp, _inpw, _inpd, _outp,
_outpw, and _outpd functions incorrectly indicate that they are included in
Msvcrt.lib (or Msvcrtx0.dll). These functions were never intended for export
from the DLL version of the C run-time library (CRT), and do not exist in that
version of the CRT.

A build of a project that uses the DLL version of the CRT may fail at link time
with LNK2001 errors and one or more of the following functions reported as
unresolved externals:

  _inp, _inpw, _inpd, _outp, _outpw, _outpd

To use these functions, you need to link with one of the static versions of the
CRT -- Libc.lib or LIBCMT.lib.
