在Linux中使用TIPC套接字时，何时应使用TIPC_ADDR_ID，TIPC_ADDR_NAME，TIPC_ADDR_NAMESEQ。有人能告诉他们之间有什么不同吗？每个地址有什么好处？

在此补丁中添加的评论中似乎可以相当清楚地解释：http://blitiri.com.ar/git/r/pytipc/c/15cae2455c1774400949069e98b3abf5ea20e311/

即：

+Addresses are expressed as (addr_type, v1, v2, v3 [, scope]);
+where addr_type can be one of:
+   TIPC_ADDR_NAMESEQ, TIPC_ADDR_MCAST, TIPC_ADDR_NAME, and TIPC_ADDR_ID;
+and scope can be one of:
+   TIPC_ZONE_SCOPE, TIPC_CLUSTER_SCOPE, and TIPC_NODE_SCOPE.
+
+
+The meaning of v1, v2 and v3 depend on the value of addr_type:
+
+   if addr_type is TIPC_ADDR_NAME:
+       v1 is the server type
+       v2 is the port identifier
+       v3 is ignored
+   if addr_type is TIPC_ADDR_NAMESEQ or TIPC_ADDR_MCAST:
+       v1 is the server type
+       v2 is the lower port number
+       v3 is the upper port number
+   if addr_type is TIPC_ADDR_ID:
+       v1 is the node
+       v2 is the ref
+       v3 is ignored
+
+Even when ignored, v3 must be present and be an integer.
