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 e.g., libncurs-
-       es_g.a, but may be compiled into any model (shared, static, profile) by
-       defining  the  symbol  TRACE.   Additionally,  some  functions are only
-       available with the wide-character configuration of the libraries.
+       The curses trace routines are used for debugging the ncurses libraries,
+       as well as applications which use the ncurses libraries.  Some  limita-
+       tions apply:
+
+       o   Aside from curses_trace, the other functions are normally available
+           only with the debugging library e.g., libncurses_g.a.
+
+           All of the trace functions may be compiled into any model  (shared,
+           static, profile) by defining the symbol TRACE.
+
+       o   Additionally,  the  functions  which use cchar_t are only available
+           with the wide-character configuration of the libraries.

Functions

        The principal parts of this interface are
 
-       o   trace, which selectively enables different tracing features, and
+       o   curses_trace, which selectively enables different tracing features,
+           and
 
        o   _tracef, which writes formatted data to the trace file.
 
-       Calling trace with a nonzero parameter creates the file  trace  in  the
-       current  directory  for output.  If the file already exists, no tracing
-       is done.
-
-       The other functions either return a pointer to a string-area (allocated
-       by the corresponding function), or return no value (such as _tracedump,
-       which implements the screen dump for TRACE_UPDATE).  The caller  should
-       not  free  these  strings, since the allocation is reused on successive
-       calls.  To work around the problem of a single  string-area  per  func-
-       tion,  some use a buffer-number parameter, telling the library to allo-
-       cate additional string-areas.
+           The other functions either return a pointer to a string-area (allo-
+           cated by the corresponding function), or return no value  (such  as

+           telling the library to allocate additional string-areas.
+
+       The curses_trace function is always available, whether or not the other
+       trace functions are available:
+
+       o   If tracing is available, calling curses_trace with a nonzero param-
+           eter updates the trace mask, and returns the previous trace mask.
+
+           When the trace mask is nonzero, ncurses creates the file "trace" in
+           the current directory for output.  If the file already  exists,  no
+           tracing is done.
+
+       o   If tracing is not available, curses_trace returns zero (0).

+           defined when building the library.
+
+           The SVr4 tracing feature is undocumented.
+
+       o   PDCurses provides traceon and traceoff, which (like SVr4)  are  al-
+           ways  available, and enable tracing to the "trace" file only when a
+           debug-library is built.
+
+           PDCurses has a short description of these functions,  with  a  note
+           that  they are not present in X/Open Curses, ncurses or NetBSD.  It
+           does not mention SVr4, but the functions'  inclusion  in  a  header
+           file section labeled "Quasi-standard" hints at the origin.
+
+       o   NetBSD  does  not  provide functions for enabling/disabling traces.
+           It  uses  environment   variables   CURSES_TRACE_MASK   and   CURS-
+           ES_TRACE_FILE  to  determine  what is traced, and where the results
+           are written.  This is available only when a debug-library is built.

+       with application names.
