标题说明了一切，这可能是一件简单的事情，但我对编程很陌生，因此这个愚蠢的问题..
我有：
printf("sourcemsg: %s", inet_ntoa(sourceMsgs[j].sin_addr));
查看保存在 sourceMsgs[j] 中的 IP 地址是否正确，所以我假设问题出在：
nbytes = sendto(s, response , reslen, 0 , (struct sockaddr *)&sourceMsgs[i],sizeof(sourceMsgs));
// (uk: save the coordinates/address of the source of the received message
// in table sourceMsgs at index nReceivedMessages).
//I'm pretty sure what I did here is wrong
int j = nReceivedMessages;
sourceMsgs[j].sin_addr = cli_addr.sin_addr;
printf("sourcemsg: %s", inet_ntoa(sourceMsgs[j].sin_addr));
nReceivedMessages++;
total += receivedValue;
printf("<Servidor> Valor recebido: %f\n", receivedValue);
//(uk: <Server> Received value)
if(nReceivedMessages == 1){
timeout = 1;
setsockopt(s, SOL_SOCKET, SO_RCVTIMEO, (char *)&timeout, sizeof(DWORD));
}
}
}
sprintf(response, "Received Messages: %f Total: %f", nReceivedMessages, total);
int reslen = sizeof(response);
for(i=0; i<nReceivedMessages; i++){
// (uk: transmit the content of variable response, the previously defined string, to
// all the destinations in table sourceMsgs).
nbytes = sendto(s, response , reslen, 0 , (struct sockaddr *)&sourceMsgs[i],sizeof(sourceMsgs));
如果帖子非常不完整，我深表歉意，但这是我的第一篇。提前感谢您的帮助
编辑：
似乎问题确实在于传递结构的长度（WSAError 10014）。现在的代码是这样的：
nbytes = sendto(s, response , strlen(response), 0 , (struct sockaddr *)&sourceMsgs[i].sin_addr, sizeof(sourceMsgs[i].sin_addr));
我不太确定该怎么做，但可能有不同的方法：
sourceMsgs[j].sin_addr = cli_addr.sin_addr;
printf("sourcemsg: %s", inet_ntoa(sourceMsgs[j].sin_addr));
nReceivedMessages++;
total += receivedValue;
因为我认为我这样做的方式是搞砸了。
