insch, winsch, mvinsch, mvwinsch - insert a character before cursor
in a curses window
#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);
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.
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.
These routines do not necessarily imply use of a hardware insert
character feature.
Note that insch, mvinsch, and mvwinsch may be macros.
These functions are described in the XSI Curses standard, Issue 4.
curses(3X).
Comparable functions in the wide-character (ncursesw) library are
described in curs_ins_wch(3X).
