Variable Attributes

Macros
#define	ATTR_ALIGNED(Bytes)   __attribute__ ((aligned(Bytes)))
	This attribute specifies a minimum alignment for the variable or structure field, measured in bytes.
#define	ATTR_PACKED   __attribute__ ((packed))
	The packed attribute specifies that a variable or structure field should have the smallest possible alignment—one byte for a variable, and one bit for a field, unless you specify a larger value with the aligned attribute.
#define	ATTR_PREPACKED
#define	ATTR_PACKED_STRUCT(x)   x __attribute__ ((packed))
