.SH DESCRIPTION
These routines insert a \fBwchar_t\fR character string
(as many characters as will fit on the line)
before the character under the cursor.
All characters to the right of the cursor are shifted right,
with the possibility of the rightmost characters on the line being lost.
No wrapping is performed.
The cursor position does not change
(after moving to \fIy\fR, \fIx\fR, if specified).
The four routines with \fIn\fR as the last argument
insert a leading substring of at most \fIn\fR \fBwchar_t\fR characters.
If \fIn\fR is less than 1, the entire string is inserted.
.PP
If a character in \fIwstr\fR is a tab, newline, carriage return or
backspace, the cursor is moved appropriately within the window.
A newline also does a \fBclrtoeol\fR before moving.
Tabs are considered to be at every eighth column.
If a character in \fIwstr\fR is another control character,
it is drawn in the \fB^\fR\fIX\fR notation.
Calling \fBwin_wch\fR after adding a control character
(and moving to it, if necessary)
does not return the control character,
but instead returns a character in the ^-representation
of the control character.
.SH NOTES
Note that all but wins_nwstr may be macros.
.PP
If the first character in the string is a nonspacing character, these
functions will fail.
XSI does not define what will happen if a nonspacing character follows
a control character.
.SH RETURN VALUE
Upon successful completion, these functions return OK.
Otherwise, they return ERR.
.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.
