Hi TTimo,
I´m sorry, my mistake.in pair.c int to = 100;
assert (nn_setsockopt (sock, NN_SOL_SOCKET, NN_RCVTIMEO, &to, sizeof (to)) >=
0);Define timeout to nn_recv, changing default behavior from -1 (infinite) to
100.
I´m very tired, and compile and recompile library confused me.
Thanks for yout attention.
Best regards,
Ranier Vilela

Hello TTimo,With pair.c
(http://tim.dysinger.net/posts/2013-09-16-getting-started-with-nanomsg.html)int
result = nn_recv (sock, &buf, NN_MSG, 0);pair.exe node0
tcp://127.0.0.1:5555pair.exe node1 tcp://127.0.0.1:5555
nn_recv won´t fill buf, and return immediatly.
If nn_recv return with empty buffer, how loop this?
nanomsg-winxp, work with tcp socket in Windows XP?
or
Is really necessary Windows 7, to get nanomsg working with tcp socket?
Best regards,

Hello Ranier,
Do you have a test case that shows this problem? Is it encountered as part of
the normal regression tests?
Looking at the documentation, you could probably ignore/disable that flag on XP
entirely. You may want to add a loop to fill up the buffer and basically
simulate what MSG_WAITALL does.
Best,TTimo

Ps. Sorry, my mistake in first message.
