can server side get the thread id of client side?

[fang zhengshu]

hi all,
I want to write a simple example in l4, and there are to task module:
client,server
in the client side, I use the interface which is inplemented in server
side.like:
int open(int fd, int flags)
I know that the client side can get the server's thread_id throw name
service. I want to ask can the server side get the client's task_id or
thread_id?
or must the client side send the thread_id to server?

thank you.
