    curs_inwstr(3x)                                                curs_inwstr(3x)

## 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 *wstr);
           int innwstr(wchar_t *wstr, int n);
           int winwstr(WINDOW *win, wchar_t *wstr);
           int winnwstr(WINDOW *win, wchar_t *wstr, int n);

           int mvinwstr(int y, int x, wchar_t *wstr);
           int mvinnwstr(int y, int x, wchar_t *wstr, int n);
           int mvwinwstr(WINDOW *win, int y, int x, wchar_t *wstr);
           int mvwinnwstr(WINDOW *win, int y, int x, wchar_t *wstr, int n);

## DESCRIPTION

           These routines return a string of  wchar_t  wide  characters  in  wstr,
           extracted starting at the current cursor position in the named window.

           The  four  functions  with  n  as  the  last  argument return a leading
           substring at most n characters long (exclusive of  the  trailing  NUL).
           Transfer  stops  at  the  end of the current line, or when n characters
           have been stored at the location referenced by wstr.

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

## NOTES

           All routines except winnwstr may be macros.

           Each  cell  in  the  window  holds a complex character (i.e., base- and
           combining-characters)  together  with  attributes  and  color.    These
           functions  store  only  the  wide  characters,  ignoring attributes and
           color.  Use in_wchstr to return the complex characters from a window.

## RETURN VALUE

           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.
