-<H2>DESCRIPTION</H2><PRE>
-       The  <B>trace</B>  routines  are  used  for debugging the ncurses
-       libraries, as well as applications which use  the  ncurses
-       libraries.   These  functions  are normally available only
-       with the debugging library <I>libncurses</I><B>_</B><I>g.a</I>, but may be com-
-       piled into any model (shared, static, profile) by defining
-       the symbol <B>TRACE</B>.
-
-       The principal parts of this interface are the  <B>trace</B>  rou-
-       tine which selectively enables different tracing features,
-       and the <B>_tracef</B> routine which writes formatted data to the
-       <I>trace</I> file.
-
-       Calling  <B>trace</B>  with  a  nonzero  parameter opens the file
-       <B>trace</B> in the current directory for output.  The  parameter
-       is formed by OR'ing values from the list of <B>TRACE_</B><I>xxx</I> def-
-       initions in <B>&lt;curses.h&gt;</B>.  These include:

+       strings, since the  allocation  is  reused  on  successive
+       calls.  To work around the problem of a single string-area
