New Revision: 2678
URL: http://svn.gna.org/viewcvs/mysqlpp?rev=2678&view=rev
Log:
Replaced recommendation in userman tutorial chapter to use
ConnectTimeoutOption to cope with connection timeouts with info on using
ReconnectOption instead. ConnectTimeoutOption controls the connect()
timeout, not the connection idle timeout. Automatic reconnection is a
better way to handle it anyway.
