</PRE>
<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.
