IPC 6678

        HeapBufMP_Params_init(&heapBufParams);
        heapBufParams.regionId       = 0;
        heapBufParams.name           = HEAP_NAME;
        heapBufParams.numBlocks      = 1;
        heapBufParams.blockSize      = sizeof(MessageQ_MsgHeader);
        heapHandle = HeapBufMP_create(&heapBufParams);
        if (heapHandle == NULL) {
            System_abort("HeapBufMP_create failed\n" );
        }

您好，在IPC例程里看到这段代码，想知道创建的heap有啥作用？
