+<H2>DESCRIPTION</H2><PRE>
+ The <STRONG>trace</STRONG> routines are used for debugging the ncurses li-
+ braries, as well as applications which use the ncurses li-
+ braries. These functions are normally available only with
+ the debugging library <EM>libncurses</EM><STRONG>_</STRONG><EM>g.a</EM>, but may be compiled
+ into any model (shared, static, profile) by defining the
+ symbol <STRONG>TRACE</STRONG>.
+
+ The principal parts of this interface are the <STRONG>trace</STRONG> rou-
+ tine which selectively enables different tracing features,
+ and the <STRONG>_tracef</STRONG> routine which writes formatted data to the
+ <EM>trace</EM> file.
+
+ Calling <STRONG>trace</STRONG> with a nonzero parameter opens the file
+ <STRONG>trace</STRONG> in the current directory for output. The parameter
+ is formed by OR'ing values from the list of <STRONG>TRACE_</STRONG><EM>xxx</EM> def-
+ initions in <STRONG><curses.h></STRONG>. These include:
+
+ TRACE_DISABLE
+ turn off tracing.
+
+ TRACE_TIMES
+ trace user and system times of updates.
+
+ TRACE_TPUTS
+ trace tputs calls.
+
+ TRACE_UPDATE
+ trace update actions, old & new screens.
+
+ TRACE_MOVE
+ trace cursor movement and scrolling.
+
+ TRACE_CHARPUT
+ trace all character outputs.
+
+ TRACE_ORDINARY
+ trace all update actions. The old and new screen
+ contents are written to the trace file for each re-
+ fresh.
+
+ TRACE_CALLS
+ trace all curses calls. The parameters for each call
+ are traced, as well as return values.
+
+ TRACE_VIRTPUT
+ trace virtual character puts, i.e., calls to <STRONG>addch</STRONG>.
+
+ TRACE_IEVENT
+ trace low-level input processing, including timeouts.
+
+ TRACE_BITS
+ trace state of TTY control bits.
+
+ TRACE_ICALLS
+ trace internal/nested calls.
+
+ TRACE_CCALLS
+ trace per-character calls.
+
+ TRACE_DATABASE
+ trace read/write of terminfo/termcap data.
+
+ TRACE_ATTRS
+ trace changes to video attributes and colors.
+
+ TRACE_MAXIMUM
+ maximum trace level, enables all of the separate
+ trace features.
+
+ Some tracing features are enabled whenever the <STRONG>trace</STRONG> pa-
+ rameter is nonzero. Some features overlap. The specific
+ names are used as a guideline.
+
+
+</PRE>
+<H2>RETURN VALUE</H2><PRE>
+ Routines which return a value are designed to be used as
+ parameters to the <STRONG>_tracef</STRONG> routine.
+
+
+</PRE>
+<H2>PORTABILITY</H2><PRE>
+ These functions are not part of the XSI interface. Some
+ other curses implementations are known to have similar,
+ undocumented features, but they are not compatible with
+ ncurses.
