This is what I use to open the connection. Its a little more fault
tolerant. netinfo is a global struct that holds all the net stuff.
bOpen = false;
allUp = false;
if (NetLibOpenCount(netInfo.netLibRefnum, &opencnt) == 0)
{
if (opencnt) {
// Verify that the interface is actually up.
err = NetLibConnectionRefresh(netInfo.netLibRefnum, false, &allUp,
&netIFErr);
if (!err && !netIFErr && allUp)
bOpen = true;
} else {
// Might be in close-wait state. Bring it out if possible
if (NetLibOpenIfCloseWait(netInfo.netLibRefnum) == 0) {
// Verify that the interface is actually up.
err = NetLibConnectionRefresh(netInfo.netLibRefnum, false,
&allUp, &netIFErr);
if (!err && !netIFErr && allUp)
bOpen = true;
}
}
}
err = 0;
// Open the library if not already open
if (!bOpen) {
NetLibClose(netInfo.netLibRefnum, true);
err = NetLibOpen(netInfo.netLibRefnum, &netIFErr);
}
if (err == netErrAlreadyOpen)
err = 0;
if (!err) {
// Open a socket
netInfo.netSocketRef = NetLibSocketOpen(netInfo.netLibRefnum,
netSocketAddrINET, netSocketTypeStream, 0, netInfo.netTimeout, &err);
}
