daqGetDeviceProperties

returns the properties for the specified device. The device is

specified by passing the name of the device in the daqName parameter. This name should be a
valid name of a configured device. The properties for the device are returned in the deviceProps
parameter. deviceProps is a pointer to user-allocated memory which will hold the device-
properties structure. This memory must have been allocated before calling this function.

For detailed device-property structure layout, refer the to Daq Device Properties Definition table.

If this function fails, make sure the daqName parameter references a valid device which is currently
configured. This can 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.
