Function Documentation

UlError ulDevGetConfig	(	DaqDeviceHandle	daqDeviceHandle,
		DevConfigItem	configItem,
		unsigned int	index,
		long long *	configValue
	)

Use with DevConfigItem to retrieve the current configuration options set for a device.

Parameters

daqDeviceHandle	the handle to the DAQ device
configItem	the configuration item to retrieve from the device
index	either ignored or an index into the configValue
configValue	the value to set the specified configuration item to

Returns

The UL error code.

UlError ulDevGetConfigStr	(	DaqDeviceHandle	daqDeviceHandle,
		DevConfigItemStr	configItem,
		unsigned int	index,
		char *	configStr,
		unsigned int *	maxConfigLen
	)

Use with DevConfigItemStr to retrieve the current configuration as a null-terminated string.

Parameters

daqDeviceHandle	the handle to the DAQ device
configItem	the configuration item to retrieve from the device
index	specifies the version type to return as an index into configItem (DevVersionType)
configStr	pointer to the buffer where the configuration string is copied
maxConfigLen	pointer to the value specifying the size of configStr made available by the user; returns the number of chars written to configStr.

Returns

The UL error code.
