Getting More Information About a Particular Device
If an adaptor provides access to multiple devices, you might need to find out more
information about the devices before you can select a device ID. The DeviceInfo field
is an array of device information structures. Each device information structure contains
detailed information about a particular device available through the adaptor.
To view the information for a particular device, you can use the device ID as a reference
into the DeviceInfo structure array. Call imaqhwinfo again, this time specifying a
device ID as an argument.
