[iolib-devel] send-to question

Hello, Under what situations does IOLib's send-to fail on a TCP socket and how does it fail? An example for a TCP receive-from is when it tries to read from a closed connection it returns 0 bytes--as oposed to read-line from a closed connection which results in a signaled END-OF-FILE condition. write-line will produce a hangup on a closed connection remotely, but what will send-to do on a closed connection remotely? Return 0? Signal a HANGUP? In practice it seems to "write" however many bytes I asked it to the nonexistent client and return the number of bytes written. I was expecting a signaled HANGUP instead. What's the deal? Thank you. -pete
