insert a \fIcurses\fR complex character in a window
.SH SYNOPSIS
.nf
\fB#include <ncursesw/curses.h>\fP
.PP
\fBint ins_wch(const cchar_t *\fIwch\fP);
\fBint wins_wch(WINDOW *\fIwin\fP, const cchar_t *\fIwch\fP);
\fBint mvins_wch(int \fIy\fP, int \fIx\fP, const cchar_t *\fIwch\fP);

.fi
.SH DESCRIPTION
These functions insert the
.I curses
complex character
.I wch
at the cursor in the specified window
.I win
(or
.BR \%stdscr ).
The character previously at the cursor and any to its right move one
cell to the right;
the rightmost character on the line is discarded.
The cursor does not advance.
.SH "RETURN VALUE"
These functions return \fBOK\fP on success and \fBERR\fP on failure.
.PP
Functions taking a
.I \%WINDOW
pointer argument fail if the pointer is
.BR NULL .
.PP
Functions prefixed with \*(``mv\*('' first perform cursor movement and
fail if the position
.RI ( y ,
.IR x )
is outside the window boundaries.
.SH NOTES
A terminal's
.B \%insert_character
.RB ( ich1 )
capability
is not necessarily employed.
.PP
\fB\%ins_wch\fP,
\fB\%mvins_wch\fP,
and
\fB\%mvwins_wch\fP
may be implemented as macros.
.SH PORTABILITY
X/Open Curses,
Issue 4 describes these functions.
.PP
SVr4 describes successful return values only as
\*(``an integer value other than \fBERR\fP\*(''.
.SH HISTORY
SVr4 (1989) implemented these functions under the names
.BR inswch ,
.BR winswch ,
.BR mvinswch ,
and
.BR mvwinswch .
.SH "SEE ALSO"
\fB\%insch\fP(3NCURSES) describes comparable functions in the
non-wide-character
.I curses
configuration.
