可以广播了吗？
------解决思路----------------------
答案呢兄弟。
------解决思路----------------------
如果你的子网掩码是255.255.255.0
你的广播地址应该是192.168.1.255吧

------解决思路----------------------

	// 设置广播===================================

	BOOL Temp=TRUE;	

	setsockopt(sockClient,SOL_SOCKET,SO_BROADCAST,(const char*)&Temp,sizeof(BOOL));

	//============================================
