/sys$common/syshlp/helplib.hlb CC, Run-time functions, getwchar  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  Reads a single wide character from the standard input (stdin).  The
  getwchar function is identical to fgetwc(stdin).

  Syntax:

       #include <wchar.h>

       wint_t getwchar (void);
