.SH DESCRIPTION
In half-delay mode,
the program waits until the user types a character or the specified
timeout interval has elapsed.
-
+.PP
Unless \fBnoecho\fR has been set,
these routines echo the character into the designated window.
-
+.PP
If the window is not a pad and has been moved or modified since the
last call to \fBwrefresh\fR,
\fBwrefresh\fR will be called before another character is read.
-
+.PP
If \fBkeypad\fR is enabled,
these functions respond to
the pressing of a function key by setting the object pointed to by
Depending on the state of the tty driver when each character
is typed, the program may produce undesirable results.
.PP
-All functions except \fBwget_wch\fR and \fBunget_wch\fR
+All functions except \fBwget_wch\fR and \fBunget_wch\fR
may be macros.
-.SH RETURN VALUES
+.SH RETURN VALUE
When
\fBget_wch\fR,
\fBwget_wch\fR,
\fBOK\fR.
Otherwise, the function returns
\fBERR\fR.
+.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.
