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 charac-
       ters 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.

SEE ALSO
       curses(3X).

       Comparable   functions   in   the  wide-character  (ncursesw)  library  are  described  in
       curs_ins_wch(3X).
