ZigBee queue structures

tszQueue

The ZigBee queue structure tszQueueis shown below.

typedef struct
{
uint32 u32Length;
uint32 u32ItemSize;
uint32 u32MessageWaiting;
void *pvHead;
void *pvWriteTo;
void *pvReadFrom;
}tszQueue;

where:

u32Lengthis the size of the queue in terms of the number of messages that it can hold
u32ItemSizeis the size of a message, in bytes
u32MessageWaitingis the number of messages currently in the queue
pvHeadis a pointer to the beginning of the queue storage area
pvWriteTois a pointer to the next free place in the storage area where a new message can be written
pvReadFromis a pointer to the next message to be read from the storage area
