Thanks for your reply. I am a beginer of libuv.
I want to use port 6883(it's just a example) send a message, so i use
uv_udp_bind but get an "Invalid argument" error. Could you help me figure
out where i am wrong . Thanks a lot : )
uv_udp_init(loop, &sendSocket);
uv_ip4_addr(ipv4.c_str(), port, &sendAddr);
uv_buf_t buffer = uv_buf_init((char *)msg.c_str(), (unsigned
int)msg.length());
struct sockaddr_in temp;
uv_ip4_addr("127.0.0.1", 6883, &temp);
uv_udp_bind(&sendSocket, (const struct sockaddr*)&temp, 0);
perror("here");
int error = uv_udp_send(&sendRequest, &sendSocket, &buffer, 1,
(const struct sockaddr *)&sendAddr, send_callback);
