DESCRIPTION
       The  ttrraaccee  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 libncursesg.a,
       but may be compiled into any model (shared, static, profile) by  defin-
       ing the symbol TTRRAACCEE.

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

       Calling ttrraaccee with a nonzero parameter opens the file ttrraaccee in the cur-
       rent directory for output.  The parameter is formed  by  OR'ing  values
       from the list of TTRRAACCEExxx definitions in <>.  These include:

       TRACEDISABLE
            turn off tracing.

       TRACETIMES
            trace user and system times of updates.

       TRACETPUTS
            trace tputs calls.

       TRACEUPDATE
            trace update actions, old & new screens.

       TRACEMOVE
            trace cursor movement and scrolling.

       TRACECHARPUT
            trace all character outputs.

       TRACEORDINARY
            trace  all  update  actions.   The old and new screen contents are
            written to the trace file for each refresh.

       TRACECALLS
            trace all curses calls.  The parameters for each call are  traced,
            as well as return values.

       TRACEVIRTPUT
            trace virtual character puts, i.e., calls to aaddddcchh.

       TRACEIEVENT
            trace low-level input processing, including timeouts.

       TRACEBITS
            trace state of TTY control bits.

       TRACEICALLS
            trace internal/nested calls.

       TRACECCALLS
            trace per-character calls.

       TRACEDATABASE
            trace read/write of terminfo/termcap data.

       TRACEATTRS
            trace changes to video attributes and colors.

       TRACEMAXIMUM
            maximum trace level, enables all of the separate trace features.

       Some  tracing  features  are  enabled  whenever  the ttrraaccee parameter is
       nonzero.  Some features overlap.  The specific  names  are  used  as  a
       guideline.

RREETTUURRNN VVAALLUUEE
       Routines  which return a value are designed to be used as parameters to
       the ttrraacceeff routine.

PPOORRTTAABBIILLIITTYY
       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.
