11 Synopsis:
12 void traceon(void);
13 void traceoff(void);
14 void PDC_debug(const char *, ...);
15
16 Description:
17 traceon() and traceoff() toggle the recording of debugging
18 information to the file "trace". Although not standard, similar
19 functions are in some other curses implementations.
20
21 PDC_debug() is the function that writes to the file, based on
22 whether traceon() has been called. It's used from the PDC_LOG()
23 macro.
