These functions are normally available only with the debugging library libncurses_g.a, but may be compiled into any model (shared, static, profile) by defining the symbol TRACE.The principal parts of this interface are the trace routine which selectively 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 current directory for output. The parameter is formed by OR'ing values from the list of TRACE_xxx definitions in <curses.h>. These include:
RETURN VALUERoutines which return a value are designed to be used as parameters to the _tracef routine.PORTABILITYThese 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 ALSOcurses(3X).
