qmss host packet descriptor

Hi TI engineer

     We have used it to deliver message between cores for quite a long time.As I understand, we just push the infor into descriptor, then transfer the point to descriptor to target by the queue,isn't it?

     So I don't understand that why we have to define the descriptor in the type of "HostPacketDescriptor"? Can I just define a struct for my application, the deliver its point by the queue?As followed code:

/**********************************************************************/

      typedef struct {

          short  myMember[16];

     }MyStruct;

     MyStruct  myStruct;

     descriptor  = pop(queue);

     memcpy(  descriptor  ,  &myStruct,  sizeof(myStruct));

    push (queue, descriptor  );

/**********************************************************************/

   Is it OK?Looking forward to your reply, thank you.
