flush 的疑问。

liaozanxu

代码如下：

print $accept $crn_char;
print $accept $some_content;
print $accept $crn_char;

我想这3个print用3个包发出去。（snoop可以看到）

但不管怎么用 $accept->autoflush(1); 或$accetp->flush();用snoop 可以看到都是一个包发出去的。

各位有没有好的办法？谢谢啦

不要连续送....要等一下..
或在中间呼叫一下flush;清空buffer...

I tried insert flush, but it is no use

print $accept $crn_char;
print $accept->flush();
print $accept $some_content;
print $accept->flush();
print $accept $crn_char;

你 syswrite 试试。

Thanks for your attention!

I also tried syswrite, but it doesn't come into effective too, even I try:

print ...
syswrite...
print...

from snoop, I can see they are all in one package too!

Until now, the only successful solution is "sleep 1" after each print, abvoius it isn't acceptable.

Now I guess, maybe the root cause is Nagel algorithm? I will try set socket option to resolve this problem. but I'm not sure.

实在不行就只好使绝招了：用 send！加 PUSH 记号。

Sorry, I don't know its usage, Could you give me an exemple?

liaozanxu

Thank you all!

the final solution is : setsockopt($accept, Socket::IPPROTO_TCP, Socket::TCP_NODELAY, 1);
