D()

#define     D(x)

Use this macro to output debugging information. x is the content as you would pass it to printf(), including braces to make the arguments appear as one argument to the macro. 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 :
