Re: CA Repeater: bind test err was "The operation completed successfully. "

Hi Freddie,

The condition test in the verify() method either calls epicsSocketDestroy() or it examines the SOCKERRNO value, so I don’t think your explanation quite works. I can’t explain what’s going on with Lewis’ machine right now, but I’m not a Windows networking expert at all. Anybody else got any ideas?

One way to fix it might be to change makeSocket() to make a copy of any socket error code and then return that (or 0 on success) rather than true/false
