 .SH DESCRIPTION
 These functions extract the complex character and rendition from
-the current position in the named window into the \fBcchar_t\fR object
+the current position in the named window into the \fBcchar_t\fP object
 referenced by wcval.
 .SH RETURN VALUE
 No errors are defined in the XSI Curses standard.
-This implementation checks for null pointers, returns ERR in that case.
-Also, the \fImv\fR routines check for error moving the cursor, returning ERR
-in that case.
-Otherwise they return OK
+This implementation checks for null pointers, returns \fBERR\fP in that case.
+Also, the \fImv\fP routines check for error moving the cursor,
+returning \fBERR\fP in that case.
+Otherwise they return \fBOK\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 NOTES
 Note that all of these routines may be macros.
 .SH PORTABILITY
 These functions are described in the XSI Curses standard, Issue 4.
