DAQmxSwitchDisconnectAll
int32 DAQmxSwitchDisconnectAll (const char deviceName[], bool32 waitForSettling);
Purpose
Terminates all active connections on the device, which places the relays into the topology reset state. You can use this function to terminate connections made by DAQmxSwitchConnect, DAQmxSwitchOpenRelays, or DAQmxSwitchCloseRelays. This function does not alter the settling time or channel usage settings. To reset those settings, use DAQmxResetDevice or DAQmxSwitchSetTopologyAndReset.
If you set waitForSettling to TRUE, this function returns only after terminating all connections. If you want to wait for settling between disconnections, use the DAQmxSwitchDisconnect function multiple times to terminate connections separately.
