       inwstr,	innwstr,  winwstr,  winnwstr,  mvinwstr, mvinnwstr, mvwinwstr, mvwinnwstr - get a
       string of wchar_t characters from a curses window

       #include <curses.h>

       int inwstr(wchar_t *str);
       int innwstr(wchar_t *str, int n);
       int winwstr(WINDOW *win, wchar_t *str);
       int winnwstr(WINDOW *win, wchar_t *str, int n);
       int mvinwstr(int y, int x, wchar_t *str);
       int mvinnwstr(int y, int x, wchar_t *str, int n);
       int mvwinwstr(WINDOW *win, int y, int x, wchar_t *str);
       int mvwinnwstr(WINDOW *win, int y, int x, wchar_t *str, int n);

       These routines return a string of wchar_t characters in wstr, extracted	starting  at  the
       current cursor position in the named window.  Attributes are stripped from the characters.
       The four functions with n as the last argument return a leading substring at most n  bytes
       long  (exclusive  of the trailing NUL).	Transfer stops at the end of the current line, or
       when n bytes have been stored at the location referenced by wstr.

       If the size n is not large enough to store a complete character, an error is generated.

       Note that all routines except winnwstr may be macros.

       All routines return ERR upon failure. Upon successful  completion,  the	*inwstr  routines
       return OK, and the *innwstr routines return the number of characters read into the string.

       Functions  with	a  "mv" prefix first perform a cursor movement using wmove, and return an
       error if the position is outside the window, or if the window pointer is null.
