Your calls looks ok.

CR_IPSOCK_ERROR means that the windows 'call


didn't work.

mysql_error() should include the error number from the socket call.

Can you print out this to check what happens.

Can you also try to connect with two mysql clients at the same time?

If you want you can use the MyODBC source to compile an own version
of mysqlclient.lib to make it easier to debug..
