curs_ins_wstr(3x)                Library calls               curs_ins_wstr(3x)




NAME

       ins_wstr,  ins_nwstr,  wins_wstr,  wins_nwstr, mvins_wstr, mvins_nwstr,
       mvwins_wstr, mvwins_nwstr - insert a wide-character string in a  curses
       window


SYNOPSIS

       #include <curses.h>

       int ins_wstr(const wchar_t *wstr);
       int ins_nwstr(const wchar_t *wstr, int n);
       int wins_wstr(WINDOW *win, const wchar_t *wstr);
       int wins_nwstr(WINDOW *win, const wchar_t *wstr, int n);

       int mvins_wstr(int y, int x, const wchar_t *wstr);
       int mvins_nwstr(int y, int x, const wchar_t *wstr, int n);
       int mvwins_wstr(WINDOW *win, int y, int x, const wchar_t *wstr);
       int mvwins_nwstr(WINDOW *win, int y, int x, const wchar_t *wstr, int n);


DESCRIPTION

       These routines insert a wchar_t character string (as many characters as
       will fit on the line) before  the  character  under  the  cursor.   All
       characters  to  the  right  of  the  cursor are shifted right, with the
       possibility of the rightmost characters on the  line  being  lost.   No
       wrapping  is  performed.   The  cursor  position does not change (after
       moving to y, x, if specified).  The four routines with n  as  the  last
       argument  insert  a  leading substring of at most n wchar_t characters.
       If n is less than 1, the entire string is inserted.

       If a character in wstr is a tab, newline, carriage return or backspace,
       the  cursor  is  moved appropriately within the window.  A newline also
       does a clrtoeol before moving.  Tabs are  considered  to  be  at  every
       eighth column.  If a character in wstr is another control character, it
       is drawn in the ^X notation.  Calling win_wch after  adding  a  control
       character  (and moving to it, if necessary) does not return the control
       character, but instead returns a character in the  ^-representation  of
       the control character.


NOTES

       Note that all but wins_nwstr may be macros.

       If  the  first character in the string is a nonspacing character, these
       functions will fail.  XSI  does  not  define  what  will  happen  if  a
       nonspacing character follows a control character.


RETURN VALUE

       Upon successful completion, these functions return OK.  Otherwise, they
       return ERR.

       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.
