NAME

       insch,  winsch, mvinsch, mvwinsch - insert a character before cursor in
       a curses window


SYNOPSIS

       #include <curses.h>

       int insch(chtype ch);
       int winsch(WINDOW *win, chtype ch);
       int mvinsch(int y, int x, chtype ch);
       int mvwinsch(WINDOW *win, int y, int x, chtype ch);


DESCRIPTION

       These routines insert the character ch before the character  under  the
       cursor.   All characters to the right of the cursor are moved one space
       to the right, with the possibility of the rightmost  character  on  the
       line  being  lost.   The insertion operation does not change the cursor
       position.


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  descrip-
       tions.

       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

       These  routines do not necessarily imply use of a hardware insert char-
       acter feature.

       Note that insch, mvinsch, and mvwinsch may be macros.


PORTABILITY

       These functions are described in the XSI Curses standard, Issue 4.
