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 sub-
       string 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  charac-
       ter, 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 com-
       bining-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.
