-<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:
-
- 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 &amp; 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
- refresh.
-
- 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 <B>addch</B>.
-
- 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 <B>trace</B>
- parameter 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 <B>_tracef</B> 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.
