Defines
#define	IDMA3_PROTOCOL_NULL   ((IDMA3_ProtocolHandle)NULL)
	NULL protocol definition.
Data Structures
struct	IDMA3_MemRec
	Record containing attributes of the IDMA3 Channel environment memory when (optionally) the IDMA3 Channel is requested with a non-NULL IDMA3_ProtocolObj. More...
struct	IDMA3_ChannelRec
	DMA Channel Descriptor to logical DMA channels. More...
struct	IDMA3_Fxns
	These fxns are used to query/grant the DMA resources requested by the algorithm at initialization time, and to change these resources at runtime. All these fxns are implemented by the algorithm, and called by the client of the algorithm. More...
struct	IDMA3_ProtocolObj
	These functions are used to determine memory requirements for and initialize the IDMA3 protocol's environment that will be allocated by the DMA manager. More...
struct	IDMA3_Obj
	IDMA3_Obj holds the private state associated with each logical DMA channel. More...
Typedefs
typedef enum IDMA3_MemType	IDMA3_MemType
	Memory space descriptors for IDMA3_MemRec.
typedef struct IDMA3_MemRec	IDMA3_MemRec
	Record containing attributes of the IDMA3 Channel environment memory when (optionally) the IDMA3 Channel is requested with a non-NULL IDMA3_ProtocolObj.
typedef struct IDMA3_Obj *	IDMA3_Handle
	Handle to "logical" DMA channel.
typedef struct IDMA3_ProtocolObj *	IDMA3_ProtocolHandle
	Handle to IDMA3 protocol object.
typedef enum IDMA3_Priority	IDMA3_Priority
	IDMA3 Priority Levels.
typedef struct IDMA3_ChannelRec	IDMA3_ChannelRec
	DMA Channel Descriptor to logical DMA channels.
typedef struct IDMA3_Fxns	IDMA3_Fxns
	These fxns are used to query/grant the DMA resources requested by the algorithm at initialization time, and to change these resources at runtime. All these fxns are implemented by the algorithm, and called by the client of the algorithm.
typedef struct IDMA3_ProtocolObj	IDMA3_ProtocolObj
	These functions are used to determine memory requirements for and initialize the IDMA3 protocol's environment that will be allocated by the DMA manager.
typedef struct IDMA3_Obj	IDMA3_Obj
	IDMA3_Obj holds the private state associated with each logical DMA channel.
Enumerations
enum	IDMA3_MemType {   IDMA3_INTERNAL,   IDMA3_EXTERNAL }
