NAME

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

SYNOPSIS

       #include <curses.h>
       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 characters as  will  fit  on  the  line)
       before  the character under the cursor, as if calling winsch(3NCURSES).  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  functions  with  n  as  the  last  argument  insert  a leading substring of at most n
       characters.  If n is less than zero, the entire string is  inserted  (stopping  on  a  NUL
       character).

       Special characters are handled as in waddch(3NCURSES).

RETURN VALUE

       All functions return the integer ERR upon failure and OK on success.

       X/Open does not define any error conditions.  This implementation returns an error

       •   if the win parameter is null or

       •   if the str parameter is null or

       •   the winsch(3NCURSES) function returns an error.

       Functions  with  a  “mv” prefix first perform a cursor movement using wmove(3NCURSES), and
       return an error if the position is outside the window, or if the window pointer is null.

NOTES

       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  Single  Unix  Specification,  Version  2  states  that  insnstr  and winsnstr perform
       wrapping.  This is probably an error, since it makes this group of functions inconsistent.
       Also, no implementation of curses documents this inconsistency.

       X/Open states that the entire string is inserted if n is less than 1.  This is probably an
       error, because it is inconsistent with other functions, and  differs  from  the  SVr4  and
       X/Open implementations on Solaris.
