rather than exiting. It is safe but redundant to check
the return value of <STRONG>initscr</STRONG> in XSI Curses.
+ If the TERM variable is missing or empty, <STRONG>initscr</STRONG> uses the
+ value "unknown", which normally corresponds to a terminal
+ entry with the <EM>generic</EM> (<EM>gn</EM>) capability. Generic entries
+ are detected by <STRONG><A HREF="curs_terminfo.3x.html">curs_terminfo(3x)</A></STRONG> and cannot be used for full-
+ screen operation. Other implementations may handle a
+ missing/empty TERM variable differently.
