[zeromq-dev] Unable to run Weather update server (wuserver.c) example

[shancat]

Not that I know of but I haven't gone that deep into zmq on Windows. You
might be sacrificing performance but I don't think there's up to date
performance information on Windows. Maybe you can do some benchmarks? If go
to http://api.zeromq.org/3-2:zmq-bind and go to the part about transports
you can go to each inbuilt transport doc page and read up.

Thanks for being supportive, one last thing if I go with C/C++ on
Windows what else will I have  to sacrifice (other than ipc://)? Can
you guide me to a reference / contents / list of zeroMQ protocols /
transports with supported platforms.

Regards,
SMA
