Function Usage
The daqGetDeviceList function will return the device names in the deviceList parameter for the number
of devices returned by the deviceCount parameter. The deviceList entry contains an array of device names
each consisting of up to 64 characters. Each device name can then be used with the daqOpen function to open the
specific device. The DaqDeviceListT parameter must point to an appropriately sized memory area which can
hold all the names for all the configured devices before calling this function. If it is not known how many devices
are configured, then call the daqGetDeviceCount function before calling this function.
If the number returned does not seem appropriate, the device configuration list should be checked via the Daq*
Configuration applet located in the Control Panel. Refer to the configuration section in your device’s user manual
for more details.
