I took the following way to manage this limitation:
In my poll() function I poll each socket.
First call to recv() function with MSG_PEEK option (read but don't remove data
from the queue) to know if there is any data to get from sockets,.
Then I call to send() function with 0 length message to know if it is able to
send data to the socket.
My problem is with the accept() function when I can't check the availability of
connection in non-intrusive way.

They have no way to multiplex among several sockets?
How can you possibly implement a decent networking application on such platform?
Maybe they have some proprietary function to do the task?
