[Xenomai] socket XDDP recvfrom timeout ?

[Xenomai] socket XDDP recvfrom timeout ?

[Laurent LEQUIEVRE]

Hello,

I try to use the socket XDDP with the posix skin to communicate from RT 
thread to non RT thread.

To get a non blocked 'recvfrom', I added the flag 'MSG_DONTWAIT', and 
it's work fine.

But how to setup a timeout for this function ?

I tried to set the flag 'SO_RCVTIEMO' by using 2 methods :

struct timeval tv;
tv.tv_sec=nb seconds
tv.tv_usec=nb micro seconds
setsockopt(socket_id,SOL_SOCKET, SO_RCVTIMEO, &tv, sizeof(tv)); --> 
doesn't work, blocked !

timeout (in nano seonds)
ioctl(socket_id, SO_RCVTIMEO, &timeout);  --> doesn't work, blocked !


Thanks for your help,

Laurent LEQUIEVRE

Just a simple reminder. The Xenomai mailing list is a "subscriber
only" mailing list. Which means you must be subscribed to be allowed
to post. And when I say you, I mean "one e-mail address". So, if you
want to use a second mail address, you must subscribe this second
mail address (and disable mail delivery if you do not want to
receive the e-mails twice).
