           insstr,  insnstr,  winsstr, winsnstr, mvinsstr, mvinsnstr,
           mvwinsstr, mvwinsnstr - insert string before cursor  in  a
           curses window

## SYNOPSIS

           #include
           int insstr(const char *str);
           int insnstr(const char *str, int n);
           int winsstr(WINDOW *win, const char *str);
           int winsnstr(WINDOW *win, const char *str, int n);
           int mvinsstr(int y, int x, const char *str);
           int mvinsnstr(int y, int x, const char *str, int n);
           int mvwinsstr(WINDOW *win, int y, int x, const char *str);
           int mvwinsnstr(WINDOW *win, int y, int x, const char *str,
           int n);

## DESCRIPTION

           These  routines insert a character string (as many charac-
           ters 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 char-
           acters  on  the line being lost.  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 sub-
           string of at most n characters.  If n<=0, then the  entire
           string is inserted.

           If  a  character in str 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 str is another control character, it is drawn
           in the ^X notation.  Calling winch 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.

## RETURN VALUE

           All  routines that return an integer return ERR upon fail-
           ure and OK (SVr4 specifies only "an  integer  value  other
           than  ERR")  upon  successful completion, unless otherwise
           noted in the preceding routine descriptions.

## NOTES

           Note that all but winsnstr may be macros.

## PORTABILITY

           These functions are described in the XSI Curses  standard,
           Issue  4,  which  adds  const qualifiers to the arguments.
           The XSI Curses error  conditions  EILSEQ  and  EILOVERFLOW
           associated  with  extended-level  conformance  are not yet
           detected (this implementation does not  yet  support  XPG4
           curses(3X), curs_clear(3X), curs_inch(3X).
