/* 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
