AllocateComponentPermutation()

CODEC_ERROR AllocateComponentPermutation	(	ALLOCATOR *	allocator,
		COMPONENT_PERMUTATION *	permutation,
		int	component_count
	)

Allocate the arrays in a component permutation.

The allocated arrays in the component permutation are initialized to all zeros.

AllocateComponentTransform()

CODEC_ERROR AllocateComponentTransform	(	ALLOCATOR *	allocator,
		COMPONENT_TRANSFORM *	transform,
		int	component_count
	)
