NAME

       insstr,  insnstr,  winsstr,  winsnstr, mvinsstr, mvinsnstr, mvwinsstr, mvwinsnstr - insert
       string before cursor 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.  All characters to the right of the cursor are
       shifted right with the possibility of the rightmost characters on  the  line  being  lost.
       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<=0,
       then the entire string is inserted.

       Special characters are handled as in addch.

RETURN VALUE

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

       X/Open  defines  no  error conditions.  In this implementation, if the window parameter is
       null or the str parameter is null, an error is returned.

       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.

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 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.
