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.  Additionally, some functions are only available
       with the wide-character configuration of the libraries.

       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.

       These functions check the NCURSES_TRACE environment  variable,  to  set
       the tracing feature as if trace was called:
              filter,  initscr, new_prescr, newterm, nofilter, ripoffline, se-
              tupterm, slk_init, tgetent

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.

SEE ALSO
       ncurses(3NCURSES).
