Macros
Initializers for a statically defined value
Each expands to a braced initializer for one Value Container, so a capability known at build time can be placed in .rodata rather than built at runtime. They are what MPIPE_STRUCTURE_DEFINE takes for each of its fields. The range forms take the bounds and the step between two consecutive values.
#define	MPIPE_VALUE_BOOLEAN(v)
	Initialize an MPIPE_TYPE_BOOLEAN value.
#define	MPIPE_VALUE_INT(v)
	Initialize an MPIPE_TYPE_INT value.
#define	MPIPE_VALUE_UINT(v)
	Initialize an MPIPE_TYPE_UINT value.
#define	MPIPE_VALUE_INT_RANGE(lo, hi, st)
	Initialize an MPIPE_TYPE_INT_RANGE value.
#define	MPIPE_VALUE_UINT_RANGE(lo, hi, st)
	Initialize an MPIPE_TYPE_UINT_RANGE value.

Enumerations
