Macro Name and Value	Description
HDF_BSP_ERR_START (-100)
HDF_BSP_ERR_NUM(v) (HDF_BSP_ERR_START + (v))
HDF_DEV_ERR_START (-200)
HDF_DEV_ERR_NUM(v) (HDF_DEV_ERR_START + (v))
HDF_WAIT_FOREVER 0xFFFFFFFF	Indicates that the function keeps waiting to obtain a semaphore or mutex.
HDF_ARRAY_SIZE(a) (sizeof(a) / sizeof((a)[0]))	Defines the array size.
HDF_KILO_UNIT 1000	Defines a time conversion unit, for example, the unit for converting from second to millisecond.
