NAME
insch, winsch, mvinsch, mvwinsch - insert a character before cursor in
a curses window
SYNOPSIS
#include <ncurses/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.
