The function <STRONG>getstr</STRONG> is equivalent to a series of calls to

terminating character is not included in the returned
- string). The resulting value is placed in the area
- pointed to by the character pointer <EM>str</EM>.

<STRONG>wgetnstr</STRONG> reads at most <EM>n</EM> 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

These functions are described in the XSI Curses standard,
Issue 4. They read single-byte characters only. The
- standard does not define any error conditions. This
- implementation returns ERR if the window pointer is null,

SVr3 and early SVr4 curses implementations did not reject
function keys; the SVr4.0 documentation claimed that "spe-

key's KEY_ value).
