DAQmxSwitchCloseRelays
int32 DAQmxSwitchCloseRelays (const char relays[], bool32 waitForSettling);
Purpose
Closes the specified relays. If you set waitForSettling to TRUE, this function waits only after closing all relays. If you want to wait for settling after closing each relay, use this function multiple times to close each relay separately.
When you operate relays directly, you circumvent the protection that channel usage types offer. Avoid using this function when you use the DAQmxSwitchConnect function or the DAQmxSwitchDisconnect function. This function does not pass the changes you make to those functions.
