Dear Florian,
This must not block.
If it does, please tell us what TIPC version you are using.
I am using TIPC -1.7.3 .The call to recv() in the server
program waits for 5 s until the matching send has been executed on the
client, before it returns.
I did not see any fcntl() O_NONBLOCK calls, so this blocks.
That is true. We are not very concerned about the blocking
nature of the socket in the function "void wait_for_server".
Thanks,
Krishna Chaitanya,

Dear all,
I have attached the simple code where I have made an attempt
at
setting the TIPC socket to work in the non-blocking mode. But, I notice
that
the recv() call is actually waiting for the matching send to be executed.
Is
there a better way of doing the same? Does TIPC support non-blocking
sockets?
Thanks,
Krishna Chaitanya K

1.7.3:
[..]
recv(5, 0x8055038, 65536, 0) = -1 EAGAIN
(where 5 is a tipc SOCK_STREAM socket)

I did not see any fcntl() O_NONBLOCK calls, so this blocks.

This must not block.
If it does, please tell us what TIPC version you are using.
