Hi 
Starting with Xenomai 2.5.x, there are couple of protocols which can be used by the rt threads for IPC 
purposes. I am playing with the xddp protocol. Apart from the examples in xenomai source tree and an 
e-mail from Philippe in xenomai-core mailing list, I couldnt find any further documentation. Do I overlook 
smt here ? Are there any other pointers which document these protocols with further details ?

The API is actually Posix - Socket based so the usage is pretty straightforward but it would be nice 
to have a list of accepted parameters for setsockopt call and what they are doing and maybe the accepted 
values of "flags" parameter which can be used for example with recvfrom() call ? It would be more comfortable 
then digging in the xenomai source code.

And in order to ask a particular question:

Any idea how to make recvfrom() call non-blocking in xddp context ? seems to be blocking per default.

Thanks & Regards

Guvenc
