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.
