The macro is automatically deleted if -DDEBUG is not passed at build time. x : debugging information. D_ASSERT#define D_ASSERT(exp, msg) The macro outputs msg if the expression exp evaluates to FALSE. exp : expression to evaluate. msg : message to output if exp fails. D_ASSERT_PTR#define D_ASSERT_PTR(ptr) The macro asserts the existence (i.e. non-NULL-ness) of the given pointer, and outpus a message if it is NULL. ptr : pointer to check. D_ENTER#define D_ENTER The macro updates internal debugging state when entering the function where this macro is used. Use it at the beginning of a function, but don't forget to properly match up D_ENTER with D_RETURN! The macro outpus the name of the entered function indented by the current nesting level. D_RETURN#define D_RETURN The macro updates internal debugging state when leaving the function where this macro is used. Use this macro wherever the function can be left, and don't forget D_ENTER. D_RETURN_#define D_RETURN_(x) Same as D_RETURN, but for return with an argument. x :
