/* Public Domain Curses */ #include <curspriv.h> RCSID("$Id: debug.c,v 1.7 2008/07/13 16:08:18 wmcbrine Exp $") /*man-start************************************************************** 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.
