Advanced >> Wait Mode

Data Type:	int32
Description:	Specifies how an NI-DAQmx Read function waits for samples to become available.

Valid values

DAQmx_Val_WaitForInterrupt	12523	Check for available samples when the system receives an interrupt service request. This mode is the most CPU efficient, but results in lower possible sampling rates.
DAQmx_Val_Poll	12524	Repeatedly check for available samples as fast as possible. This mode allows for the highest sampling rates at the expense of CPU efficiency.
DAQmx_Val_Yield	12525	Repeatedly check for available samples, but yield control to other threads after each check. This mode offers a balance between sampling rate and CPU efficiency.
DAQmx_Val_Sleep	12547	Check for available samples once per the amount of time specified in Sleep Time.
