DigitalSingleChannelReaderEndMemoryOptimizedReadSingleSampleMultiLine Method

Handles the end of an asynchronous read initiated with BeginMemoryOptimizedReadSingleSampleMultiLine(AsyncCallback, Object, Boolean) and retrieves the read samples.

Namespace: NationalInstruments.DAQmx
Assembly: NationalInstruments.DAQmx (in NationalInstruments.DAQmx.dll) Version: 20.7.40.49302

public bool[] EndMemoryOptimizedReadSingleSampleMultiLine(
	IAsyncResult asyncResult
)

Public Function EndMemoryOptimizedReadSingleSampleMultiLine ( 
	asyncResult As IAsyncResult
) As Boolean()

asyncResult: Type: SystemIAsyncResult
An IAsyncResult that represents an asynchronous call started by calling BeginMemoryOptimizedReadSingleSampleMultiLine(AsyncCallback, Object, Boolean).

Type: Boolean
A 1D array of Boolean samples from the task. Each element of the array corresponds to a digital line in the channel.

Exception	Condition
ArgumentException	If data is or is uninitialized; asyncResult is or is not an instance of IAsyncResult returned from a call to BeginMemoryOptimizedReadSingleSampleMultiLine(AsyncCallback, Object, Boolean).
DaqException	The NI-DAQmx driver returned an error during the asynchronous operation.
OutOfMemoryException	There is not enough memory to carry out this operation.

If you call this method before the asynchronous read is complete, it waits for the read to complete before returning.

NI-DAQmx read and write methods time out after the amount of time specified by the Timeout property on the task you are reading from or writing to.
