NAME

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


SYNOPSIS

       #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);


DESCRIPTION

       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 char-
       acters.  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.


NOTES

       Note that all routines except winnwstr may be macros.


RETURN VALUE

       All routines return ERR upon failure. Upon successful com-
       pletion, 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  move-
       ment  using  wmove, and return an error if the position is
       outside the window, or if the window pointer is null.
