curs_insch(3X)                                                  curs_insch(3X)

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
       descriptions.

       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
       character feature.

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

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