 \fBwgetnstr\fR reads at most \fIn\fR characters, thus preventing a possible
 overflow of the input buffer.  Any attempt to enter more characters (other
 than the terminating newline or carriage return) causes a beep.  Function
 keys also cause a beep and are ignored.  The \fBgetnstr\fR function reads
 from the \fIstdscr\fR default window.

 The user's erase and kill characters are interpreted.  If keypad
 mode is on for the window, \fBKEY_LEFT\fR and \fBKEY_BACKSPACE\fR

+.PP
 SVr3 and early SVr4 curses implementations did not reject function keys;
 the SVr4.0 documentation claimed that "special keys" (such as function
 keys, "home" key, "clear" key, \fIetc\fR.) are "interpreted", without
 giving details.  It lied.  In fact, the `character' value appended to the
 string by those implementations was predictable but not useful
 (being, in fact, the low-order eight bits of the key's KEY_ value).

 The functions \fBgetnstr\fR, \fBmvgetnstr\fR, and \fBmvwgetnstr\fR were
 present but not documented in SVr4.
