Remarks

This method searches the current set of managed data connections for one whose connection properties are equivalent to the specified connection information. If a connection is found, it is returned. If a connection is not found, a new one is created and the new one is returned.

The state of the returned connection is undefined; it remains in the same state that was previously left by another client.
