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
described in curs_ins_wch(3X).
