关于fread超时问题

[zxhong]

有一开源代码，建立socket后，用fdopen打开sockid，返回FILE指针

以后对该socket的操作都是以流文件方式如：fread，fwrite等

我的问题是如何对fread操作进行超时处理？select，setsockopt似乎都不行

select，setsockopt似乎都不行??
你是怎么处理的

[zxhong]

setsockopt(s, SOL_SOCKET, SO_RCVTIMEO, &seltime, sizeof(seltime));

[zxhong]

connect成功后

setsockopt(s, SOL_SOCKET, SO_RCVTIMEO, &seltime, sizeof(seltime));

[jixingzhong]

int TimeOut=6000; //设置发送超时6秒
if(::setsockopt(cClient,SOL_SOCKET,SO_SNDTIMEO,(char *)&TimeOut,sizeof(TimeOut))==SOCKET_ERROR){
return 0;
}
......

select怎麽不行了？

int WaitResponse(int sock_fd, int timeout)
{
fd_set rfds;
struct timeval tv;
int ret = FALSE;
int selectRet = -1;

memset(&tv, 0, sizeof(struct timeval));

FD_ZERO(&rfds);
FD_SET(sock_fd, &rfds);
tv.tv_sec = timeout;
tv.tv_usec = 0;
selectRet = select(sock_fd + 1, &rfds, NULL, NULL, &tv);
if(selectRet == -1){
ret = FALSE;
}
else if(selectRet > 0 && FD_ISSET(sock_fd, &rfds)){
ret = TRUE;
}
else{
ret = FALSE;
}
return ret;
}
