Question

I am working on Embedded C . I am stuck with pointer structure ….

Structures are given below ..

/*structure 1*/
ZPS_tsAplApsmeBindingTableType *psAplApsmeAibBindingTable;

/*structure 2*/
typedef struct
{
    ZPS_tsAplApsmeBindingTableCache* psAplApsmeBindingTableCache;
    ZPS_tsAplApsmeBindingTable* psAplApsmeBindingTable;
}ZPS_tsAplApsmeBindingTableType;

/*structure3*/
typedef struct
{
   uint64  u64SourceAddress;
   ZPS_tsAplApsmeBindingTableEntry* pvAplApsmeBindingTableEntryForSpSrcAddr;
   uint32 u32SizeOfBindingTable;
}ZPS_tsAplApsmeBindingTable;

/*structure 4*/
typedef struct
{
   ZPS_tuAddress  uDstAddress;
   uint16  u16ClusterId;
   uint8   u8DstAddrMode;
   uint8   u8SourceEndpoint;
   uint8   u8DestinationEndPoint;
} ZPS_tsAplApsmeBindingTableEntry;

I have declared ZPS_tsAplApsmeBindingTableType *p; but i want to access ZPS_tsAplApsmeBindingTableEntry structure values… How could i do that??

Can anyone tell me the difference between

ZPS_tsAplApsmeBindingTable* psAplApsmeBindingTable

and

ZPS_tsAplApsmeBindingTable *psAplApsmeBindingTable;

Thanks ….

Answer 1

1. p->psAplApsmeBindingTable->pvAplApsmeBindingTableEntryForSpSrcAddr->someField
2. No difference.

PS. That code is really, really ugly.
