-<H2>DESCRIPTION</H2><PRE>
- The function <B>getstr</B> is equivalent to a series of calls to
- <B>getch</B>, until a newline or carriage return is received (the
- terminating character is not included in the returned
- string). The resulting value is placed in the area
- pointed to by the character pointer <I>str</I>.
-
- <B>wgetnstr</B> reads at most <I>n</I> 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 <B>getnstr</B> function reads
- from the <I>stdscr</I> default window.
-
- The user's erase and kill characters are interpreted. If
- keypad mode is on for the window, <B>KEY_LEFT</B> and
- <B>KEY_BACKSPACE</B> are both considered equivalent to the user's
- kill character.
-
- Characters input are echoed only if <B>echo</B> is currently on.
- In that case, backspace is echoed as deletion of the pre-
- vious character (typically a left motion).
-
-
-</PRE>
-<H2>RETURN VALUE</H2><PRE>
- All routines return the integer <B>ERR</B> upon failure and an <B>OK</B>
- (SVr4 specifies only "an integer value other than <B>ERR</B>")
- upon successful completion.
-
-
-</PRE>
-<H2>NOTES</H2><PRE>
- Note that <B>getstr</B>, <B>mvgetstr</B>, and <B>mvwgetstr</B> may be macros.
-
-
-</PRE>
-<H2>PORTABILITY</H2><PRE>
- These functions are described in the XSI Curses standard,
- Issue 4. They read single-byte characters only. The
- standard specifies that they return <B>ERR</B> on failure, but
- the single error condition <B>EOVERFLOW</B> associated with
- extended-level conformance is not yet returned (the XSI
- curses support for multi-byte characters is not yet pre-
- sent).
-
- SVr3 and early SVr4 curses implementations did not reject
- function keys; the SVr4.0 documentation claimed that "spe-
- cial keys" (such as function keys, "home" key, "clear"
- key, <I>etc</I>.) 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 <B>getnstr</B>, <B>mvgetnstr</B>, and <B>mvwgetnstr</B> were pre-
- sent but not documented in SVr4.
