给出有问题代码！请大虾帮看看！Linux下客户端socket(TCP阻赛方式)，为什么设置不了超时！

[ecwaychina]

int timeout = 15000;
if (setsockopt(sockfd,SOL_SOCKET,SO_RCVTIMEO,(char *)&timeout,sizeof(int))== -1){
write_normal_msg(" do_iptvclient_socket: Set Socket Receive timeout fail");
}
else
{
write_normal_msg(" do_iptvclient_socket: Set Socket Receive timeout Success");
}
if (setsockopt(sockfd,SOL_SOCKET,SO_SNDTIMEO,(char *)&timeout,sizeof(int))== -1){
write_normal_msg(" do_iptvclient_socket: Set Socket Send timeout fail");
}
else
{
write_normal_msg(" do_iptvclient_socket: Set Socket Send timeout Success");
}

总是报错!
write_normal_msg(" do_iptvclient_socket: Set Socket Receive timeout fail");
write_normal_msg(" do_iptvclient_socket: Set Socket Send timeout fail");

超时值应该是一个timeval结构，而不是一个整形值。具体结构可以看select的man手册，它也使用了这个结果。
