Remarks
This function is called by the Connection Manager and processed by the Connection Service Provider.
The Connection Manager will free all resources associated with the connection immediately after this call returns. Therefore, the Connection Service Provider must not return until all resources associated with the application are no longer used.
Before calling this function, the Connection Manager changes the CM_CONNECTION_STATE to CMCS_DISCONNECTING. When this function returns, the Connection Manager changes the CM_CONNECTION_STATE to CMCS_DISCONNECTED.
It is important that this function return as soon as possible, as delays will be apparent to other applications and to users.
The Connection Manager serializes calls to CmCspConnect, CmCspDisconnect and CmCspGetConnectionInfo.
