Hi, I run into exactly the same problem. So far I am still unable to find a workable solution for non-blocking socket connection.
Apparently, the NetLibSocketOptionGet(netSocketOptSockErrorStatus) does not work at all. I once try the NetLibSocketAddr() to see if the socket is connected. However, NetLibSocketAddr() returns the remote address as soon as DNS is performed, but before the actual socket connection takes place. Thus, I am able to decide if a socket is connected after performing a non-blocking connect. Is there any good solution? I have also tried calling NetLibSocketConnect() repeatedly on a non-blocking socket. However, it returns netErrInternal on the Palm Simulator. So is there a workable non-blocking socket connection on the PalmOS? Thanks a lot.
