curs_inswch, inswch, winswch, mvinswch, mvwinswch - Insert a wchar_t character before the character under the cursor in a Curses window
#include <curses.h>
int inswch(
chtype wch
);
int winswch(
WINDOW *win,
chtype wch
);
int mvinswch(
int y,
int x,
chtype wch
);
int mvwinswch(
WINDOW *win,
int y,
int x,
chtype wch
);
These routines insert the character
wch,
which contains a wide character, 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. These routines
do not change the cursor position after moving to
y,
x, if specified. This does not imply use of the hardware insert-character
feature.
The header file <curses.h> automatically includes the header file <stdio.h>.
Note that inswch, mvinswch, and mvwinswch may be macros.
The routines described on this reference page are among the MNLS Curses
functions that are not included in the X/Open Curses CAE specification. MNLS
routines are supported only for backward compatibility reasons. Compaq
recommends the use of the
*ins_wch
functions in new applications
(see
curs_ins_wch(3)).
All routines return the integer
ERR
upon
failure and an integer value other than
ERR
upon
successful completion.
