NAME
       _tracef,	_tracedump, _traceattr,	_traceattr2, _nc_tracebits,
       _tracechar, _tracechtype, _tracechtype2,	_tracemouse, trace - curses
       debugging routines

SYNOPSIS
       #include	<curses.h>

       void _tracef(const char *format,	...);
       void _tracedump(const char *label, WINDOW *win);
       char *_traceattr(attr_t attr);
       char *_traceattr2(int buffer, chtype ch);
       char *_nc_tracebits(void);
       char *_tracechar(int);
       char *_tracechtype(chtype ch);
       char *_tracechtype2(int buffer, chtype ch);
       char *_tracemouse(const MEVENT *event);
       void trace(const	unsigned int param);

DESCRIPTION
       The  trace  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 libncurses_g.a,
       but may be compiled into	any model (shared, static, profile) by	defin-
       ing the symbol TRACE.

       The  principal  parts of	this interface are the trace routine which se-
       lectively enables different tracing features, and the  _tracef  routine
       which writes formatted data to the trace	file.

       Calling trace with a nonzero parameter opens the	file trace in the cur-
       rent directory for output.  The parameter is formed  by	OR'ing	values
       from the	list of	TRACE_xxx definitions in <curses.h>.  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 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 addch.

       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 trace parameter is
       nonzero.	 Some features overlap.	 The specific  names  are  used	 as  a
       guideline.

RETURN VALUE
       Routines	 which return a	value are designed to be used as parameters to
       the _tracef routine.

PORTABILITY
       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.
