To debug any C++ or C programs include the file
debug.h
and in your 'Makefile' define DEBUG_STR, DEBUG_PRT, DEBUG_MEM to
turn on the traces from the debug.h functions.
When you remove the '-DDEBUG_STR' etc.. then the debug function calls are set to
((void)0) i.e. NULL,
hence it has no impact on final production release version of project. You can generously
use the debug functions in your programs and it will not increase the size of production
executable.
See the file
debug.cpp
for implementation of debug routines.
And see the file
my_malloc.cpp
for sample which uses debug.h and debug functions.
