#define STRINGIFY ( S ) #S

Converts a macro parameter into a string.

Parameters

S	Expression to be converted

Returns: stringified version of S

#define assert_size	(	TYPE,
		SIZE
	)	static_assert(sizeof(TYPE) == (SIZE), "Wrong size for " STRINGIFY(TYPE))

Statically ensure (at compile time) that a data type (or variable) has the expected size.

Parameters

TYPE	The type to be checked
SIZE	Expected size in bytes

#define assert ( EXP )

Value:

    do { \
        if (__builtin_expect(!(EXP), 0)) { \
            assertion_failed(STRINGIFY(EXP), __func__, __FILE__, __LINE__); \
        } \
    } while (false)

Ensure (at execution time) an expression evaluates to true, print an error message and stop the CPU otherwise.

Parameters

EXP	The expression to be checked

#define kernelpanic ( MSG )

Value:

    do { \
            DBG << "PANIC: '" << (MSG) << "' in " << __func__ \
                << " @ " << __FILE__ << ":" << __LINE__ \
                << flush; \
		Core::die(); \
    } while (0)

Print an error message in the debug window and stop the current core.

Parameters

MSG	error message
