/* Name: debug
*
* Synopsis:
* void traceon(void);
* void traceoff(void);
* void PDC_debug(const char *, ...);
*
* Description:
* traceon() and traceoff() toggle the recording of debugging
* information to the file "trace". Although not standard, similar
* functions are in some other curses implementations.
*
* PDC_debug() is the function that writes to the file, based on
* whether traceon() has been called. It's used from the PDC_LOG()
* macro.
*
* Portability X/Open BSD SYS V
* traceon - - -
* traceoff - - -
* PDC_debug - - -
