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.
