# curs_insch 3x

    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.

           Comparable functions  in  the  wide-character  (ncursesw)  library  are
