Public Function BeginReadSingleSamplePulseTicks ( 
	callback As AsyncCallback,
	state As Object
) As IAsyncResult

Parameters

callback: Type: SystemAsyncCallback
An optional asynchronous callback that is called when the read is complete. Specify if you do not want a callback when the read is complete.
state: Type: SystemObject
A user-provided object that distinguishes this asynchronous read request from other requests. Use this parameter to provide information to the callback. Specify if you do not need to pass any additional information to the callback.

To get the read data or any exceptions that occurred during an asynchronous read initiated with BeginReadSingleSamplePulseTicks(AsyncCallback, Object), call EndReadSingleSamplePulseTicks(IAsyncResult) with the returned IAsyncResult.

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.
