//==================================================================== // 函数: wf_ping
//-------------------------------------------------------------------- // 描述: 判断指定的IP地址是否能PING通,此函数还没有判断IP格式是否正确,
// 实际上还应该加上这一功能,才比较完善
//-------------------------------------------------------------------- // 参数:
// value string as_ipaddress 只能判断IP地址,不能判断机器名
// value string as_echomsg 随便一个值都可以
//-------------------------------------------------------------------- // 返回值: boolean
ULong lul_address, lul_handle
