heap configuration when applying MessageQ in Syslink

Thanks for your answer. But I still cannot understand the configuration through the documents you provide. In fact I just cannot figure out relation between the heap configuration and the definition of the message. 

In the MessageQ example of Syslink, the message struct is defined as follow:

typedef struct {
MessageQ_MsgHeader reserved;
UInt32 cmd;       //unsigned int 
SharedRegion_SRPtr buf;
} App_Msg;

According to the definition, actually two questions bother me.

First, Are there any connections between the definition of message struct and the configuration of heap. If there are connections (which I believe), how the message size affect the size and number of the heap.

Second, in the example, the member named buf is unused. What this member for?  

Now, I am planning to send nine float numbers to DSP through MessageQ, and then get one float number back. So I think I might need two message structs, and how should I configure the heap according to my need?

Thank for your explanation again and look forward to your reply!

Hi,

This "HeapBufMP_create" function used to allocate memory(Fixed size buffers memory allocator) for app messages from heap which allocated for syslink by linux and it is calculated by "block size * no of blocks"

MAU is memory allocation unit.
