 .SH DESCRIPTION
 .SH DESCRIPTION

-These routines copy \fIchstr\fR into the window image structure at and after
-the current cursor position.  The four routines with \fIn\fR as the last
-argument copy at most \fIn\fR elements, but no more than will fit on the line.
-If \fBn\fR=\fB-1\fR then the whole string is copied, to the maximum number of
-characters that will fit on the line.
+These functions copy the (null-terminated)
+\fIchstr\fR array
+into the window image structure
+starting at the current cursor position.
+The four functions with \fIn\fR as the last
+argument copy at most \fIn\fR elements,
+but no more than will fit on the line.
+If \fBn\fR=\fB\-1\fR then the whole array is copied,
+to the maximum number of characters that will fit on the line.

-The window cursor is \fInot\fR advanced, and these routines work faster than
-\fBwaddnstr\fR.  On the other hand, they do not perform any kind of checking
-(such as for the newline, backspace, or carriage return characters), they do not
-advance the current cursor position, they do not expand other control characters
-to ^-escapes, and they truncate the string if it crosses the right margin,
-rather then wrapping it around to the new line.
-.SH RETURN VALUES
-All routines return the integer \fBERR\fR upon failure and \fBOK\fR on success
-(the SVr4 manuals specify only "an integer value other than \fBERR\fR") upon
-successful completion, unless otherwise noted in the preceding routine
-descriptions.
