Namespace: NationalInstruments.DAQmx
Assembly: NationalInstruments.DAQmx (in NationalInstruments.DAQmx.dll) Version: 20.7.45.49302

public CIDataTime[] ReadMultiSamplePulseTime(
	int numberOfSamples
)

Public Function ReadMultiSamplePulseTime ( 
	numberOfSamples As Integer
) As CIDataTime()

numberOfSamples: Type: SystemInt32
The number of samples to read. If you set numberOfSamples to -1 for a continuous acquisition, the read retrieves all samples available in the buffer at the time of the read. If you set numberOfSamples to -1 for a finite acquisition, the read behavior is set by the ReadAllAvailableSamples property of the DaqStream you are reading from.

Type: CIDataTime
A 1D array of pulse samples in terms of time from the task. Each element of the array corresponds to a sample from the task.

Exception	Condition
DaqException	The NI-DAQmx driver returned an error.
OutOfMemoryException	There is not enough memory to carry out this operation.

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.
