.SH DESCRIPTION
-These functions write the (null-terminated) character string
-\fIstr\fP on the given window.
-It is similar to calling \fBwaddch\fP once for each byte in the string.
+.B waddstr
+writes the characters of the (null-terminated) string
+.I str
+to the window
+.IR win .
+Its process is similar to calling \fB\%waddch\fP(3X) for each
+.I char
+in
+.IR str .
+Control characters are processed as in \fB\%waddch\fP(3X).
.PP
-The \fImv\fP functions perform cursor movement once, before writing any
-characters.
-Thereafter, the cursor is advanced as a side-effect of writing to the window.
+.B waddnstr
+writes at most
+.I n
+characters,
+or until a terminating null character occurs in
+.IR str .
+If
+.I n
+is \-1,
+.B
+.B waddnstr
+writes the entire string.
.PP
-The four functions with \fIn\fP as the last argument
-write at most \fIn\fP bytes,
-or until a terminating null is reached.
-If \fIn\fP is \-1, then the entire string will be added.
+\fB\%ncurses\fP(3X) describes the variants of these functions.
.SH RETURN VALUE
-All functions return the integer \fBERR\fP upon failure and \fBOK\fP on success.
+These functions return
+.B OK
+on success and
+.B ERR
+on failure.
.PP
-X/Open does not define any error conditions.
-This implementation returns an error
+X/Open Curses does not specify any error conditions.
+.I \%ncurses
+returns an error
.bP
-if the window pointer is null or
+if the window pointer is
+.BR NULL ,
.bP
-if the string pointer is null or
+if the string pointer is
+.BR NULL ,
+or
.bP
-if the corresponding calls to \fBwaddch\fP return an error.
-.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.
-If an error is returned by the \fBwmove\fP,
-no characters are added to the window.
+if an internal \fB\%waddch\fP(3X) call returns an error.
.PP
-If an error is returned by \fBwaddch\fP
-(e.g.,
-because the window is not large enough,
-or an illegal byte sequence was detected)
-only part of the string may be added.
-Aside from that,
-there is a special case in \fBwaddch\fP where an error may be
-returned after successfully writing a character to the lower-right corner
-of a window when \fBscrollok\fP(3X) is disabled.
+Functions prefixed with \*(``mv\*('' first perform cursor movement and
+fail if the position
+.RI ( y ,
+.IR x )
+is outside the window boundaries.
.SH NOTES
All of these functions except \fBwaddnstr\fP may be macros.
.SH PORTABILITY
-These functions are described in the XSI Curses standard, Issue 4.
+X/Open Curses,
+Issue 4 describes these functions.
