Question

43 syntax error before `;'
event message_t *Receive.receive (message_t *msg,void *payload,uint8_t len) {
40 test_send_msg_t * btrpkt;
41 if ( (len == sizeof(test_send_msg_t)) && (TOS_NODE_ID == 1) ) {
42 recFlags = TRUE;
43 memcpy(btrpkt,(test_send_msg_t*)payload,sizeof(test_send_msg_t);
44 printf("listening the message %d \n",btrpkt->count);
45 showDate = btrpkt->number>>2;
46 showDate |= btrpkt->colour;
47 call Update.change(&showDate);
48 }
49 }

Answer 1

memcpy(btrpkt,(test_send_msg_t*)payload,sizeof(test_send_msg_t); 这行最右边少了括回去的小括号啊
