linux和windows下用setsockopt设置send(), recv() 超时的参数的一点区别

2008-12-15 20:18

linux:

struct timeval timeout={3,0};//3s

int ret=setsockopt(sock_fd,SOL_SOCKET,SO_SNDTIMEO,&timeout,sizeof(timeout));

int ret=setsockopt(sock_fd,SOL_SOCKET,SO_RCVTIMEO,&timeout,sizeof(timeout));

如果ret==0 则为成功,-1为失败,这时可以查看errno来判断失败原因

int recvd=recv(sock_fd,buf,1024,0);

if(recvd==-1&&errno==EAGAIN)

{

printf("timeout\n");

}

windows:

int timeout = 3000; //3s

int ret=setsockopt(sock_fd,SOL_SOCKET,SO_SNDTIMEO,&timeout,sizeof(timeout));

int ret=setsockopt(sock_fd,SOL_SOCKET,SO_RCVTIMEO,&timeout,sizeof(timeout));
