如何把buf里收到的端口号作为action里的UDP连接send目标？

basler

socket脚本，客户端先用tcp与服务器连接，有服务器处获得一随机端口号，然后再用udp与服务器的这一随机端口号连接(其实是realplayer和server)。怎么才能把分别在buf和脚本里的两个东西联系起来啊。设关联吗？设完之后，并不能影响action.c文件啊，恳请高手指教。

多谢版主了，帮大忙了

basler

lrs_get_socket_attrib得到的端口应该是从作为参数的socket处得到的。
我的意思是，怎么把一个soket里receive到的buf的值，作为另一个UDPsoket，send里的参数

buf5里receive到的

“..client_port=6970;server_port=31558\r\n\r\n”


发送udp的soket

lrs_create_socket("socket1", "UDP", "LocalHost=6970", LrsLastArg);
lrs_send("socket1", "buf6", "TargetSocket=172.20.23.20:31558", LrsLastArg);

用lr_eval_string试试。
