 .SH SYNOPSIS
-#include <curses.h>
-.sp
-\fBint ins_wch(const cchar_t *\fR\fIwch\fR\fB);\fR
-.br
-\fBint wins_wch(WINDOW *\fR\fIwin, const cchar_t *\fR\fIwch\fR\fB);\fR

-.br
-\fBint mvwins_wch(WINDOW *\fR\fIwin, int \fR\fIy, int \fR\fIx, const cchar_t *\fR\fIwch\fR\fB);\fR
-.SH DESCRIPTION
-These routines, insert the complex character \fIwch\fR with rendition
-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.
-.SH RETURN VALUE
-If successful, these functions return OK.
-If not, they return ERR.

+\fB#include <curses.h>\fP
 .PP
-Functions with a "mv" prefix first perform a cursor movement using
-\fBwmove\fP, and return an error if the position is outside the window,
-or if the window pointer is null.
-.SH ERRORS
-No errors are defined.

+.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 ,
