Detailed Description

Internal APIs for utility operations.

Defines
#define	TIVX_ALIGN(value, align) ((((value)+((align)-1U))/(align))*(align))
	Macro to align a 'value' to 'align' units.

#define	TIVX_FLOOR(value, align) (((value)/(align))*(align))
	Macro to floor a 'value' to 'align' units.

#define	TIVX_DEFAULT_STRIDE_Y_ALIGN (16U)
	Macro to specify default alignment to use for stride in Y-direction. More...

#define	TIVX_TYPE_IS_SCALAR(type) (((vx_enum)VX_TYPE_INVALID < (type)) && ((type) < (vx_enum)VX_TYPE_SCALAR_MAX))
	Used to determine if a type is a scalar.

#define	TIVX_TYPE_IS_STRUCT(type) (((type) >= (vx_enum)VX_TYPE_RECTANGLE) && ((type) < (vx_enum)VX_TYPE_KHRONOS_STRUCT_MAX))
	Used to determine if a type is a struct.

#define	TIVX_TYPE_IS_OBJECT(type) (((type) >= (vx_enum)VX_TYPE_REFERENCE) && ((type) < (vx_enum)VX_TYPE_KHRONOS_OBJECT_END))
	Used to determine if a type is an Khronos defined object.

#define	TIVX_TYPE_IS_TI_OBJECT(type) (((type) >= (vx_enum)VX_TYPE_VENDOR_OBJECT_START) && ((type) < (vx_enum)VX_TYPE_VENDOR_OBJECT_END))
	Used to determine if a type is TI defined object.

#define	TIVX_MAGIC (0xFACEC0DEU)
	A magic value to look for and set in references.

#define	TIVX_BAD_MAGIC (42U)
	A magic value to look for and set in references. Used to indicate a free'ed reference.

#define	VX_CHECK_PARAM(ptr, size, type, align) ((NULL != ptr) && (size == sizeof(type)) && (((vx_size)ptr & align) == 0U))
	A parameter checker for size and alignment.
