daqGetDeviceProperties
DLL Function daqGetDeviceProperties(LPSTR daqName, DaqDevicePropsT *deviceProps);
C daqGetDeviceProperties(LPSTR daqName, DaqDevicePropsT *deviceProps);
Visual BASIC VBdaqGetDeviceProperties( daqName$, deviceProps as DaqDevicePropsT)
Delphi daqGetDeviceProperties( daqName: string; var deviceProps: DaqDevicePropsT)
daqName Pointer to a character string representing the name of the device for which to retrieve
properties
Parameters
deviceCount Number of devices returned in the device list
Returns DerrNoError No error (see the API Error Codes table at the end of this chapter).

Program References None
Used With All devices
Description
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.
