NAME         top

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

SYNOPSIS         top

       #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         top

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

       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         top

       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         top

       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.
