I had a problem of the udpsend object which causes “udpsend: socket
method unsuccessful” error. There were the same reports before and it
has not been fixed yet.
After a few hours investigation, I found that “host” message causes
this error. My solution is to use multiple udpsend objects in a poly~
object. (See the attached patch.) But I can’t use this technique if I
don’t know all IP addresses to be sent. I hope C74 will fix this
problem at the object level.
