curs_inwstr(3X)                                           curs_inwstr(3X)

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
       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         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.
