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
