linux:
1
struct timeval timeout=
{3,0};//3s
2
3 int ret=setsockopt(sock_fd,SOL_SOCKET,SO_SNDTIMEO,&timeout,sizeof(timeout));
4
5 int ret=setsockopt(sock_fd,SOL_SOCKET,SO_RCVTIMEO,&timeout,sizeof(timeout));
6
7 如果ret==0 則為成功,-1為失敗,這時可以查看errno來判斷失敗原因
8
9 int recvd=recv(sock_fd,buf,1024,0);
10
11 if(recvd==-1&&errno==EAGAIN)

15 printf("timeout\n");
