.SH DESCRIPTION
The function
\fIn\fP
characters, letting the application prevent overflow of the
input buffer.
+.SH RETURN VALUE
+All of these functions return the integer \fBOK\fP upon successful completion.
+If unsuccessful, they return \fBERR\fP.
+.PP
+X/Open defines no error conditions.
+.PP
+In this implementation,
+these functions return an error
+.bP
+if the window pointer is null,
+.bP
+if its timeout expires without having any data, or
+.bP
+if the associated call to
+\fBwget_wch\fP
+failed.
+.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
Any of these functions other than
\fBwgetn_wstr\fP
.PP
These functions cannot return \fBKEY_\fP values because there
is no way to distinguish a \fBKEY_\fP value from a valid \fBwchar_t\fP value.
-may be macros.
-.SH RETURN VALUE
-All of these functions return the integer \fBOK\fP upon successful completion.
-If unsuccessful, they return \fBERR\fP.
-.PP
-X/Open defines no error conditions.
-.PP
-In this implementation,
-these functions return an error
-.bP
-if the window pointer is null, or
-.bP
-if its timeout expires without having any data.
-.bP
-if the associated call to
-\fBwget_wch\fP
-failed.
-.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 PORTABILITY
These functions are described in The Single Unix Specification, Version 2.
No error conditions are defined.
X/Open Curses does not specify what happens if the length \fIn\fP is negative.
.bP
For analogy with \fBwgetnstr\fP,
-ncurses 6.2 uses a limit (based on \fBLINE_MAX\fP).
+\fI\%ncurses\fP 6.2 uses a limit (based on \fBLINE_MAX\fP).
.bP
Some other implementations (such as Solaris xcurses) do the same,
while others (PDCurses) do not allow this.
.bP
-NetBSD 7 curses imitates ncurses 6.1 in this regard,
+NetBSD 7 curses imitates \fI\%ncurses\fP 6.1 in this regard,
treating a \fB\-1\fP as an indefinite number of characters.
