乙個簡單的多執行緒socket

碼了2個小時多，終於弄完了。用的編輯器是qt creator ，突然發現在qt creator上，也支援這些底層的c語言。在linux上除錯無誤。寫這個，也算是自己讀書的記錄吧！

#include #include #include #include #include #include #include #include #include #define port 1234

struct arg *arg;

int main(void)

setsockopt(listenfd,sol_socket,so_reuseaddr,&opt,sizeof(opt));

bzero(&server,sizeof(server));

server.sin_family = af_inet;

server.sin_port = htons(port);

server.sin_addr.s_addr= htonl(inaddr_any);

while(1)

arg = (struct arg *)malloc(sizeof (struct arg));

arg->connfd = connectfd;

memcpy((void *)&arg->client,&client,sizeof(client));

{recvbuf[recvlen] = '\0';

printf("receive clent (%s) message:%s\n",client_name,recvbuf);
