Macro Definition Documentation

LINEAR_EVAL

#define LINEAR_EVAL	(		name,
			val )

Value:

linearization_eval(name.array, name.nb, (val))

Macro to call linearization on a LINEAR_TAB or sLinearFlexArray typedef.

MISRA C:2012 Deviations

Local legitimate use derogation authorized for:
Rule-20.7 - Required: Enclosed macro parameters expansion (misra-c2012-20.7)
Justification: Result expansion of name wouldn't produce the desired structured access expansion.

LINEAR_TAB

#define LINEAR_TAB	(		name,
			nbElem )

Value:

    typedef struct sLinear##name {  \
    DWORD   nb;                 \
    SDWORD  array[nbElem][2];   \
} sLinear##name;

Pattern tab typedef declaration with name catenation and nbElem max array elements.
