ASSERT

#define ASSERT	(		condition,
			returnValue
	)

Value:

do {                                                                         \
    if (!(condition)) {                                                        \
      return (returnValue);                                                    \
    }                                                                          \
  } while (0)

Checks the condition, and if the assert fails the supplied returnValue will be returned in the calling function.

// Make sure 'addr' is within range
ASSERT(addr <= MAX_ADDR, ERROR_ADDRESSOUTOFRANGE);

ASSERT_STATUS

#define ASSERT_STATUS

(

sts

)

Value:

do {                                                                         \
    err_t status = (sts);                                                      \
    if (ERROR_NONE != status) {                                                \
      return status;                                                           \
    }                                                                          \
  } while (0)

Checks the supplied err_t value (sts), and if it is not equal to ERROR_NONE the sts value will be returned.

This macro is useful to check if a function returned an error without bloating your own code with endless "if (error) {...}".

// If anything other than ERROR_NONE is returned by tsl2561Enable()
// this macro will log the error and exit the function returning the
// error_t value.
ASSERT_STATUS(tsl2561Enable());
